That smells like a CLASSPATH problem where your application is not

Actually application team, they are deploying two applications one with
towl (which you are already aware) the other one is (towl-app) they have
defined seperate server.xml for both.


Separate server.xml files means that you have to have two separate 
Tomcat processes.



Name:server.lbg.com
Address:  192.168.200.120
Aliases:  example.lbg.com


Name:server.lbg.com
Address:  192.168.200.120
Aliases:  example-app.lbg.com

which means we have two aliases for server.lbg.com , earlier we were
concentrating only on one example.lbg.com , now i wanted to somehow enable
access as the same for the other one also
https://example-app.lbg.com --> https://server.lbg.com:8444/towl-app

So i created iptable rule in the sameway as before redirect 443 to 8444 and
i have the urls working same as example.lbg.com

Both the server.xml files are here

/git/towl/apachetomcat/conf/server.xml
/git/towl-app/apachetomcat/conf/server.xml --> I changed the port of
connectors and everything

But now when i try to access https://example.lbg.com --> I get webpage of
https://example-app.lbg.com and sometimes i get webpage of
https://example.lbg.com after refresh itself which is wierd

May i know why this is happening. If we fix this then I am thinking to
disable the unwated urls leaving the required ones. for example the below
ones. I think that would be easier ? rather than redirecting or aliasing-->
Because we noticed that towl application is already pointing with
https://example.lbg.com

https://server.lbg.com:8443
   https://example-lbg.com:8443
   <https://example.lbg.com/towl>
<https://server.lbg.com/towl>

kindly suggest us a fix.


The best fix is to deploy the two applications normally without any 
funny business. Put both applications into webapps/ with no  
elements in server.xml and let them deploy. Use the correct URLs to 
access them. It's obviously some internal thing to your company because 
nobody is going to use :8443 in the real world.


I'm sorry, but it seems like you are being given arbitrary and weird 
requirements almost as a game.

Let me know if its fine for you and here is what I did.

1)  



Don't do this. Just put towl.war into webapps/ and let it auto-deploy.
What you are doing here is double-deploying your "towl" application:
once as "" (ROOT) and once as "/towl". Remove this from server.xml.






Okay.


2) I have towl application and towl.war under webapps directory
3) added  proxy port and proxyname to connector

  
 proxyPort="8443" proxyName="server.lbg.com

5) restarted tomcat
6) can access all the urls https://server.lbg.com:8443 
<https://server.lbg.com:8443>, https://server.lbg.com 
<https://server.lbg.com>, https://server.lbg.com:8443/towl 
<https://server.lbg.com:8443/towl>, https://server.lbg.com/towl 
<https://server.lbg.com/towl>

https://example.lbg.com <https://example.lbg.com>, 
https://example.lbg.com:8443/towl <https://example.lbg.com:8443/towl>, 
https://example.lbg.com/towl <https://example.lbg.com/towl>


Unfortunately aliasing still doesnot work https://example.lbg.com 
<https://example.lbg.com> --> https://server.lbg.com:8443/towl 
<https://server.lbg.com:8443/towl> and many urls works


The "aliasing" will always be weird. IMO it's better to redirect. If you 
change to redirect, does everything *work*, even if you don't like how 
the browser's URL bar displays?

AIUI, you can put all of the above in conf/rewrite.config and configure
the  under your  just as you had it before.

If you want aliasing and not redirection, then you don't want the [R]
flag. IMO, you should really do a redirect. If you don't, then the
application and the browser disagree about the base URL and all
kinds of
things like that.

Your application uses whatever internal URLs it wants. Are you building
those yourself, or are you asking Tomcat for the e.g. hostname, etc.? If
it's Tomcat, this is where the proxyName and proxyPort come in.



   - Yes, I have not built these UrLs before. It’s was working from the
very
beginning. As. I mentioned we are not able to reach goal or whatever.

Rather than saying redirection, I would say it’s aliasing.



Please be specific. "Aliasing" (to me) means "the URL does to the right
place but doesn't change in the browser's URL" and "redirection" (to
everybody) means "HTTP 301 or 302 response to a new URL".

Instead of moving applications or changing tomcat configuration it’s easier

to achieve with reverse proxy ?

https://example.lbg.com/ to https://server.lbg.com:8443/towl



This will be a nightmare. Do not try to rewrite URLs using a reverse
proxy. You should redirect users to the right place if necessary. You can
use a reverse-proxy if you want, but it won't be any less complicated than
having Tomcat do it.

I think your rewrite.config file just needs a few tweaks:

# Redirect everything that is not server.lbg.com to
# server.lbg.com. Don't worry about /towl yet.
RewriteCond %{HTTP_HOST} !^server\.lbg\.com$
RewriteRule ^/(.*) https://server.lbg.com:8443/$1 [R=301,L]

# Redirect anything that isn't already going to /towl
# to go to /towl
RewriteCond %{REQUEST_URI} !^/towl
RewriteRule ^/(.*) https://server.lbg.com:8443/towl/$1 [R=301,L]

The application should be deployed as towl.war (or towl/ directory). You
should listen on ports 80, 443, and 8443, and you should always end up at
the right place. You should have proxyPort="8443" and proxyName="
server.lbg.com" in your .

You will not need a ROOT context, since the rewrite will take care of that
for you.

Hi Chris,

You are right. We need aliasing here which means the URL in the browser
does not change.
May I know where should I put the below rewrite files ?

# Redirect everything that is not server.lbg.com to
# server.lbg.com. Don't worry about /towl yet.
RewriteCond %{HTTP_HOST} !^server\.lbg\.com$
RewriteRule ^/(.*) https://server.lbg.com:8443/$1 [R=301,L]

# Redirect anything that isn't already going to /towl

Hi Chris,

Tried the below steps. I have the redirection working. But the URL is not
in the browser anymore.

1)   
   

2) /conf/Catalina/localhost --> I added the below in rewrite.config

RewriteCond %{HTTP_HOST} ^example\.lbg\.com$
RewriteCond %{REQUEST_URI} !^/towl$
RewriteRule ^/(.*) https://server.lbg.com:8443/towl [R=301,L]


The problem with this is that it can redirect forever.

/towl/foo -> /towl/towl/foo -> /towl/towl/towl/foo and so on.

Your "stop criteria" ( !^/towl$ ) needs to be more like !^/towl/ without 
the $.



Then it redirects from https://example.lbg.com -->
https://server.lbg.com:8443/towl but the application team raised a concern
the

- alias https://example.lbg.com/--> url stays in the browser


IMHO removing the port number is always the preferred solution.

If https://example.lbg.com/ isn't returning a 301 response, then 
something is not quite right with your configuration.



- towl indexer uses the internal address https://
server.lbg.com.8443/towl rsp.
localhost:8443/towl

can we achieve this with tomcat or we need to setup an reverse proxy here.


Your application uses whatever internal URLs it wants. Are you building 
those yourself, or are you asking Tomcat for the e.g. hostname, etc.? If 
it's Tomcat, this is where the proxyName and proxyPort come in.

Re: Regarding Tomcat url redirection

[lavanya tech]

Hi Chris,

Tried the below steps. I have the redirection working. But the URL is not
in the browser anymore.

1)   
  

2) /conf/Catalina/localhost --> I added the below in rewrite.config

RewriteCond %{HTTP_HOST} ^example\.lbg\.com$
RewriteCond %{REQUEST_URI} !^/towl$
RewriteRule ^/(.*) https://server.lbg.com:8443/towl [R=301,L]

Then it redirects from https://example.lbg.com -->
https://server.lbg.com:8443/towl but the application team raised a concern
the

   - alias https://example.lbg.com/--> url stays in the browser
   - towl indexer uses the internal address https://
   server.lbg.com.8443/towl rsp.
   localhost:8443/towl

can we achieve this with tomcat or we need to setup an reverse proxy here.
Pleaes kindly suggest

Thanks,
Lavanya

Hi Chris,

Sorry, If I did confuse. It’s important that
https://server.lbg.com:8443/towl is always working. Goal is not to disable
/towl, but just redirect or aliasing

https//example.lbg.com/ to https://server.lbg.com:8443/towl

 No, this is wrong. Since this is the "towl" application and not ROOT,
 you want to map /* and not /towl/* because the application will never
 see the /towl/ as it's an application/context prefix that Tomcat will
 remove.

 If webapps/towl is being created, then it's happening for some other
 reason. Do you have anything under conf/Catalina/*/towl.xml which points
 to a WAR file or something? If so, remove that.

I'm sorry, I'm still confused as to which way you want things.

Do you want to redirect /towl -> / or do you want to redirect / - > /towl?

Or does it depend upon the hostname? It would really be better if you

Before you do anything with redirecting, can you just make sure you are

This should allow you to reach the application at both
https://example.lbg.com/ and https://server.lbg.com/ as well as both of
those with port 8443.

Then use the applications and make sure they are working as expected.
Then, we'll add the /towl handling.

Hi Chris,

Somehow made it work now i can only access urls as you mentioned before
https://example.lbg.com and https://server.lbg.com with port 8443 and with

 https://example.lbg.com/towl and https://server.lbg.com/towl --> I have an

So i think we need to make work https://example.lbg.com/ to

Hi Chris,

Where are you defining the RewriteValve itself?

Defined rewritevalve here

This is the exact opposite of the stated goal.

You said you wanted server.lbg.com/towl to be redirected to 
example.lbg.com/ but this does the opposite.


I also wouldn't both to check the protocol. Let's save this until after 
the ROOT application is working as expected.

Where are you defining the RewriteValve itself?

If this is being handled by the ROOT servlet then I think it's right.

No, this is wrong. Since this is the "towl" application and not ROOT, 
you want to map /* and not /towl/* because the application will never 
see the /towl/ as it's an application/context prefix that Tomcat will 
remove.



 
 
 
 
 

Also I noticed that even if I rename the towl application to ROOT, when i
call the url with https://example.lbg.com/towl --> this towl directory is
getting created under webapps by default


If webapps/towl is being created, then it's happening for some other 
reason. Do you have anything under conf/Catalina/*/towl.xml which points 
to a WAR file or something? If so, remove that.

Before you do anything with redirecting, can you just make sure you are 
only deploying ROOT.war and nothing else?


This should allow you to reach the application at both 
https://example.lbg.com/ and https://server.lbg.com/ as well as both of 
those with port 8443.


Then use the applications and make sure they are working as expected. 
Then, we'll add the /towl handling.

Good, that significantly reduces the complexity required, since you can
do it will a single process (Tomcat) in a single environment.


So I need follow both 4a/b and 5a/b steps here or any of them ?

If I setup exactly by using below steps , then I should access both the

If you visit either hostname with /towl, you will be redirected to

no redirect will take place... unless you specifically make arrangements

Hi Chris,

1)proxyPort="443" and proxyName="example.lbg.com" to the connector

4) added this in web.xml file of /webapps/towl/web.xml/

Here's what you have to do in order to support this odd configuration.

1. Configure your firewall to route port 443 -> 8443. I suspect this is
already done.

2. Deploy Tomcat on server.lbg.com with a  on port 8443. This
is the default, so there shouldn't be anything to do. I suspect this is
already done. You should set proxyPort="443" and proxyName="
example.lbg.com" in your . This will ensure that any URLs
generated by Tomcat or your application will point to
https://example.lbg.com/ and not to server.lbg.com or have a port number
or whatever.

3. Re-name your application directory or WAR file from towl -> ROOT (upper
case is important). So if you have tomcat/webapps/towl re-name that to
tomcat/webapps/ROOT or if you have tomcat/webapps/towl.war re-name that to
tomcat/webapps/ROOT.war.

The last thing to do is get /towl to re-direct to /. There are a few ways
of doing that.

4a. Configure your application (now called ROOT and deployed on / and not
/towl anymore) to handle the /towl URL and specifically redirect this back
to /. This is oddly specific and has the application trying to redirect to
itself which is weird.

4b. Create a new application called towl or towl.war which will be
deployed on /towl and have THAT redirect to /. I think this is cleaner
because you can call the application anything you'd like and it will still
work. You don't have to match URL patterns yourself, you just re-name the
WAR file if you suddenly want to use /towl2 instead of /towl.

There are several ways to redirect.

5a. Use the rewrite valve and map /(*) to (global redirect) /\1. A few
notes: (1) the (*) means "capture this string" and \1 means "put the string
back. This allows you to redirect /towl/foo/bar to /foo/bar instead of
losing the /foo/bar. This syntax may not be perfect, adapt it to your
needs. (2) Remember that the towl application is deployed on /towl so you
don't want to redirect /towl/foo/bar you only want redirect /foo/bar since
the URL will be relative to the current context (/towl). Got that? Finally,
(3) you need to use a global redirect that does *NOT* redirect back to the
/towl application. Normally, if you redirect to /foo you'll get an
application-relative redirect from something like a rewrite
valve/filter/whatever. Take care to redirect relative to the SERVER and not
to the application.

5b. Write your own servlet to do a specific redirect.

I hope that helps,

Is that a typo? You want specifically https://server.lbg.com/towl and

   — It’s not the Typo the requirements are still the same.


Okay.

Do server and example both resolve to the same IP?


2) Hence I added firewall rule to redirect port 443 to 8443. And the url
https://example.lbg.com started working but its pointing to
https://server.lbg.com:8443 indeed and not https://server.lbg.com:8443/towl

But then they wanted the point 1 to have it. If I understood correctly. So
basically to achieve this we wanted a reverse proxy setup ?

I didnot define any additional host in server.xml file on just left to
default to  local host.


Here's what you have to do in order to support this odd configuration.

1. Configure your firewall to route port 443 -> 8443. I suspect this is 
already done.


2. Deploy Tomcat on server.lbg.com with a  on port 8443. This 
is the default, so there shouldn't be anything to do. I suspect this is 
already done. You should set proxyPort="443" and 
proxyName="example.lbg.com" in your . This will ensure that 
any URLs generated by Tomcat or your application will point to 
https://example.lbg.com/ and not to server.lbg.com or have a port number 
or whatever.


3. Re-name your application directory or WAR file from towl -> ROOT 
(upper case is important). So if you have tomcat/webapps/towl re-name 
that to tomcat/webapps/ROOT or if you have tomcat/webapps/towl.war 
re-name that to tomcat/webapps/ROOT.war.


The last thing to do is get /towl to re-direct to /. There are a few 
ways of doing that.


4a. Configure your application (now called ROOT and deployed on / and 
not /towl anymore) to handle the /towl URL and specifically redirect 
this back to /. This is oddly specific and has the application trying to 
redirect to itself which is weird.


4b. Create a new application called towl or towl.war which will be 
deployed on /towl and have THAT redirect to /. I think this is cleaner 
because you can call the application anything you'd like and it will 
still work. You don't have to match URL patterns yourself, you just 
re-name the WAR file if you suddenly want to use /towl2 instead of /towl.


There are several ways to redirect.

5a. Use the rewrite valve and map /(*) to (global redirect) /\1. A few 
notes: (1) the (*) means "capture this string" and \1 means "put the 
string back. This allows you to redirect /towl/foo/bar to /foo/bar 
instead of losing the /foo/bar. This syntax may not be perfect, adapt it 
to your needs. (2) Remember that the towl application is deployed on 
/towl so you don't want to redirect /towl/foo/bar you only want redirect 
/foo/bar since the URL will be relative to the current context (/towl). 
Got that? Finally, (3) you need to use a global redirect that does *NOT* 
redirect back to the /towl application. Normally, if you redirect to 
/foo you'll get an application-relative redirect from something like a 
rewrite valve/filter/whatever. Take care to redirect relative to the 
SERVER and not to the application.


5b. Write your own servlet to do a specific redirect.

I hope that helps,

I would *highly* recommend that you pick either /towl or / and not try to

just deploy towl.war and ROOT.war as copies of each other). If you try to

The goal should be that "moving" the application only means changing DNS
and everything else works as expected.

If you want to use port 443 (the default port for HTTPS) then you will
need to change Tomcat to bind to port 443 (if that's allowed on your OS)
or arrange to have port 443 routed to port 8443. You may need additional
configuration in Tomcat (specifically: proxyPort) to avoid having Tomcat
generate URLs with ":8443" in them.

Looking forward to your reply.


If Tomcat is listening on port 8443 then you will need to include that 
in your URL, period. If you want to allow URLs without a port number, 
you will have to arrange to have something listening on port 443.


On Windows, Tomcat can listen directly on port 443. On UNIX and 
UNIX-like systems, you won't be able to do this without running Tomcat 
as root WHICH YOU ABSOLUTELY SHOULD NOT DO.


There are other ways to get port 443 working, but I'll need to know more 
about your environment. The port issue is "easier" than figuring out 
whatever is going on with your DNS, aliases, etc. so I would recommend 
we fix one thing at a time.

I'm not sure. Is it possible you have dismissed this error in the past
and the browser is remembering that? Try this with a different web
browser or maybe with curl from the command-line to see what happens.


Why https://server.lbg.com/towl or https://example.lbg.com/towl -->

How it

should work with New SAN certificate ?


You don't need to worry about the port number or application name, only
the hostname is a part of the SAN.

You will never be able to make a secure request to anything other than
server.lbg.com without seeing an error. I highly recommend adding the
other hostname as a SAN to your certificate if you really want to
support this.

Even if you wanted https://example.lbg.com/whatever to return an HTTP

Yes, it should.

CNAME *is* DNS.

Whenever possible, use hostnames and not IP addresses as SANs. It's

more

flexible that way, and users get to see hostnames instead of IP

addresses.

Re: Regarding Tomcat url redirection

[lavanya tech]

Hi Chris,

Can you tell me how to do the below ? How should I setup Tomcat in
server.xml ?


If you want to use port 443 (the default port for HTTPS) then you will
need to change Tomcat to bind to port 443 (if that's allowed on your OS)
or arrange to have port 443 routed to port 8443. You may need additional
configuration in Tomcat (specifically: proxyPort) to avoid having Tomcat
generate URLs with ":8443" in them.

Looking forward to your reply.

Thanks,
Lavanya

Hi Chris,

There is no issues with browser, because I tested with different browsers
and it all works fine. I am sure that there is no issue with the
certificate.
 Because I was able to establish successful connections with port 8443, it
just doesnot work with out port

 curl  https://example.lbg.com/towl
curl: (56) Received HTTP code 504 from proxy after CONNECT
curl: (56) Received HTTP code 504 from proxy after CONNECT


If you want to use port 443 (the default port for HTTPS) then you will
need to change Tomcat to bind to port 443 (if that's allowed on your OS)
or arrange to have port 443 routed to port 8443. You may need additional
configuration in Tomcat (specifically: proxyPort) to avoid having Tomcat
generate URLs with ":8443" in them.

If Tomcat is listening to port 8443, then you need to use port 8443 to 
make a request. The cert doesn't cover port number, so you can still use it.


If you want to use port 443 (the default port for HTTPS) then you will 
need to change Tomcat to bind to port 443 (if that's allowed on your OS)

Re: Regarding Tomcat url redirection

[lavanya tech]

Hi Chris,

One question / doubt:

As I mentioned earlier, the below URLS already working in the browser
> https://server.lbg.com:8443/towl
> https://example.lbg.com:8443/towl -> redirect ( which means when I hit in
browser) it points to https://server.lbg.com:8443/towl ---> To be frank,
even I donot need redirect here, not sure why it redirects.

My question is why its working even though SAN is not registered with the
certificate ? It doesnot even throw warning in the browser.

Why https://server.lbg.com/towl or https://example.lbg.com/towl --> How it
should work with New SAN certificate ?

Thanks,
Lavanya

Lavanya,

You are right, example.lbg.com is CNAME record.


Okay, thanks for clearing that up.


I dont have any SAN configured for the certificate. The certificate is

You will never be able to make a secure request to anything other than 
server.lbg.com without seeing an error. I highly recommend adding the 
other hostname as a SAN to your certificate if you really want to 
support this.


Even if you wanted https://example.lbg.com/whatever to return an HTTP 
302 redirect to https://server.lbg.com/whatever, the user would see a 
certificate hostname mismatch error which is ugly. It's best to make it 
work without users seeing ugly things.



So if i just request new certificate with SAN it should work ? If yes, I
will request for it and follow your steps as below suggested.


Yes, it should.


Should i use CName record or DNS? Does it make difference?


CNAME *is* DNS.

Whenever possible, use hostnames and not IP addresses as SANs. It's more 
flexible that way, and users get to see hostnames instead of IP addresses.

This will only redirect (HTTP 302) requests to http://yourhost/anything
to https://yourhost/anything *if the application specifically requests
CONFIDENTIAL transport*. It doesn't just redirect everything by default. If
you want it to redirect everything, you'll need to set that up e.g. using
RewriteValve. There are other options, too.

Do i need additional SSL certificate for the https://example.lbg.com  to

make it work ?



If you don't want your browser to complain, you will need at least one TLS
certificate that contains every Subject Alternative Name (SAN) for every
possible hostname you expect to use with this service. You ca do it with
multiple certificates as well, but a single cert with multiple SANs is less
work.

Do i need to set up an additional web server for this like apache or nginx

for redirecting requests?



No.

Please stop saying "redirect" because it sounds like you almost never mean
"HTTP 30x redirect" and that's confusing everything.

I *think* you only need the following:

1. A TLS certificate with the following SANs:

   * server.lbg.com
   * example.lbg.com
   * localhost (you shouldn't do this)

2. DNS configured for all hostnames:

   * server.lbg.com -> A 192.168.100.20
   * example.lgb.com -> A 192.168.100.20

3. Tomcat configured with a single  which is the default virtual
host. Note that this is the *default Tomcat configuration* and doesn't need
to be changed from the default.

4. Tomcat configured with your certificate like this:


  


  


If your SANs are configured properly, this should allow you to connect
using any of these URLs:

$ curl https://server.lbg.com/towl/login.jsp

   (returns login page)

$ curl https://example.lbg.com/towl/login.jsp

   (returns login page)

If your application's web.xml contains something like this:

   
 
   theapp
   /*
 
 
   CONFIDENTIAL
 
   

... then these URLs insecure HTTP URLs should redirect your clients:

$ curl http://server.lbg.com/towl/login.jsp

   (returns HTTP 302 redirect to https://server.lbg.com/towl/login.jsp)

$ curl https://server.lbg.com/towl/login.jsp

Re: Regarding Tomcat url redirection

Hi Chris,

Thanks for the reply.

Local host means the machine i am logged in to server.lbg.com

You are right, example.lbg.com is CNAME record.

I dont have any SAN configured for the certificate. The certificate is
requested for only server.lbg.com

So if i just request new certificate with SAN it should work ? If yes, I
will request for it and follow your steps as below suggested.

Should i use CName record or DNS? Does it make difference?

I tried to adding the below to  server.xml as below, but that doesnot seems
to work.

 


This will only redirect (HTTP 302) requests to http://yourhost/anything 
to https://yourhost/anything *if the application specifically requests 
CONFIDENTIAL transport*. It doesn't just redirect everything by default. 
If you want it to redirect everything, you'll need to set that up e.g. 
using RewriteValve. There are other options, too.



Do i need additional SSL certificate for the https://example.lbg.com  to
make it work ?


If you don't want your browser to complain, you will need at least one 
TLS certificate that contains every Subject Alternative Name (SAN) for 
every possible hostname you expect to use with this service. You ca do 
it with multiple certificates as well, but a single cert with multiple 
SANs is less work.



Do i need to set up an additional web server for this like apache or nginx
for redirecting requests?


No.

Please stop saying "redirect" because it sounds like you almost never 
mean "HTTP 30x redirect" and that's confusing everything.


I *think* you only need the following:

1. A TLS certificate with the following SANs:

  * server.lbg.com
  * example.lbg.com
  * localhost (you shouldn't do this)

2. DNS configured for all hostnames:

  * server.lbg.com -> A 192.168.100.20
  * example.lgb.com -> A 192.168.100.20

3. Tomcat configured with a single  which is the default virtual 
host. Note that this is the *default Tomcat configuration* and doesn't 
need to be changed from the default.


4. Tomcat configured with your certificate like this:

   
 
   
   
 
   

If your SANs are configured properly, this should allow you to connect 
using any of these URLs:


$ curl https://server.lbg.com/towl/login.jsp

  (returns login page)

$ curl https://example.lbg.com/towl/login.jsp

  (returns login page)

If your application's web.xml contains something like this:

  

  theapp
  /*


  CONFIDENTIAL

  

... then these URLs insecure HTTP URLs should redirect your clients:

$ curl http://server.lbg.com/towl/login.jsp

  (returns HTTP 302 redirect to https://server.lbg.com/towl/login.jsp)

$ curl https://server.lbg.com/towl/login.jsp

  (returns HTTP 302 redirect to https://example.lbg.com/towl/login.jsp)

I don't think you need any use of the RewriteValve unless you want to 
handle sending HTTP 302 redirect responses to insecure requests without 
specifying the CONFIDENTIAL transport-guarantee in your application's 
web.xml file. But I don't see any reason NOT to have that in there.

Redirecting is fine.

Perhaps you should take a step back and decide: what do you actually
want, here? You might be trying to solve problem X by applying solution
Y, and you've already decided that solution Y is correct so you are
trying to get help with that.

Perhaps ask for help with Problem X?

For example, "I don't want users to have to type the name of my
application to reach it so I want example.com/ to go to my application
instead of example.com/myapp/".

Or, "I have multiple domains and I want all of them to redirect to the
canonical domain example.com and to go to me web application /myapp so
everything goes to example.com/myapp/".

Re: Regarding Tomcat url redirection

[lavanya tech]

Hi  Chris,

Sorry I understood wrongly here with regards to my environment, Let me
start from the beginning. I donot want to use redirect at all. I simply
wanted to force apache tomcat to use both localhost and dns name of the
localhost via url.
I have DNS resollution as below.

server.lbg.com --> localhost

nslookup server.lbg.com (localhost)
Name:server.lbg.com
Address:  192.168.100.20
alias: example.lbg.com

We have working the below urls working:
https://server.lbg.com:8443/towl
https://example.lbg.com:8443/towl --> redirects to
https://server.lbg.com:8443/towl  --> still works --> we have SSL
configured for the same but this SSL certificate doesnot have additional
DNS setup.
But I would need to somehow  access https://example.lbg.com --> which means
I would need to access via 443 here ?

I tried to adding the below to  server.xml as below, but that doesnot seems
to work.


-->

Do i need additional SSL certificate for the https://example.lbg.com  to
make it work ?

Do i need to set up an additional web server for this like apache or nginx
for redirecting requests?

I look forward to your feedback.

Thanks and Best Regards,
Lavanya

"You'd have to use a glob/regex if

There is nothing in your configuration or question that suggests that 
the hostname in the request is relevant, but you are making it a 
*requirement* that the request contains a specific Host header. IF you 
don't actually need that, why do you have it?

Your rewrite configuration says that you have to be using host
"example.com" but your request goes to www.example.com. Your
configuration should only redirect a request such as:

$ curl -v http://example.com:/something

HTTP/1.1 301 Moved Permanently
...
Location: https://www.example.com:/example

If you make a request like:

$ curl -v http://www.example.com:/something

I wouldn't expect a redirect because of your "host" condition. The
"%{HTTP_HOST} example.com" looks at the entire Host header and not just
anything that ends in "example.com". You'd have to use a glob/regex if
you wanted to check for [anything and maybe nothing.]example.com.

You'd also have to make sure that your application is serving responses
to requests to / which is why I'm recommending you use the ROOT web
application name instead of "towl".

It's best not to define any  in server.xml. I would remove this
 entirely and allow Tomcat to auto-reploy from your
webapps/towl directory. If you need this application to be deployed as
the ROOT context (on / and not /towl) then you should re-name
/git/app/apache-tomcat-10.1.11/webapps/towl to
/git/app/apache-tomcat-10.1.11/webapps/ROOT

You also don't need a  for example.com as well as adding an
 for the same domain (though this is probably to anonymize the
configuration). You can feel free to simply use the "localhost" 
as the default  and deploy everything into it. This makes your
configuration changes relative to a stock Tomcat less significant and
easier to apply to new versions if/when necessary.

Hi Chris,

I have already a Root folder /git/app/apache-tomcat-10.1.11/webapps, I see
the files index.jsp and index.jsp has below configuration.
So should I add server.xml under ROOT folder aswell with localhost and
example.com such that both the urls are accessible. ? Please suggest

<% response.sendRedirect("/towl"); %>

So i am not sure if the redirect url helps or if its correct


Your rewrite configuration says that you have to be using host 
"example.com" but your request goes to www.example.com. Your 
configuration should only redirect a request such as:


$ curl -v http://example.com:/something

HTTP/1.1 301 Moved Permanently
...
Location: https://www.example.com:/example

If you make a request like:

$ curl -v http://www.example.com:/something

I wouldn't expect a redirect because of your "host" condition. The 
"%{HTTP_HOST} example.com" looks at the entire Host header and not just 
anything that ends in "example.com". You'd have to use a glob/regex if 
you wanted to check for [anything and maybe nothing.]example.com.


You'd also have to make sure that your application is serving responses 
to requests to / which is why I'm recommending you use the ROOT web 
application name instead of "towl".

It's best not to define any  in server.xml. I would remove this
 entirely and allow Tomcat to auto-reploy from your
webapps/towl directory. If you need this application to be deployed as
the ROOT context (on / and not /towl) then you should re-name
/git/app/apache-tomcat-10.1.11/webapps/towl to
/git/app/apache-tomcat-10.1.11/webapps/ROOT

You also don't need a  for example.com as well as adding an
 for the same domain (though this is probably to anonymize the
configuration). You can feel free to simply use the "localhost" 
as the default  and deploy everything into it. This makes your
configuration changes relative to a stock Tomcat less significant and
easier to apply to new versions if/when necessary.

Can you give full paths to both server.xml and rewrite.config, re-post

rewrite.config?

Have you looked at the log files after start?

Re: Regarding Tomcat url redirection

[lavanya tech]

Hi Chris,

Thank you very much. I removed  for example.com as well as adding an
 in server.xml
I copied context.xml file
/git/app/apache-tomcat-10.1.11/webapps/towl/META-INF/context.xml
Removed < in rewrite.config files.

But still I dont redirect the URL.

For your information






*nslookup alias.example.com 
gives-->Non-authoritative answer:Name: www.example.com
Address:  192.168.200.10Aliases:  alias.example.com
*


Just to give some information here, *www.example.com
* has alias* "alias.example.com
"*
But https://www.example.com:/example --> works fine with out issues but
the alias doesnot works (https://alias.example.com)
So i am not sure if the redirect url helps or if its correct

Looking for some suggestions.

Thanks
Ammu

modified the server.xml as below in tomcat config, and the below

 example.com
 
 
 
 
 example.com
 
 https://www.servercom:/example/$1 [R=301,L]


1. That isn't valid XML.

2. Where in the Tomcat docs does it say you can nest re-write rules in a 
Host element (or any other element)?



 
 
 
 



You need to configure the RewriteValve.

Tomcat url redirection

*Support team,

I'm working with an application that uses apache tomcat 6 to serve the
website. I've installed the application and tomcat on a Windows 2003
server and everything is working fine.For instance I want
http://events.mydomain.xxx/ to
go to http://events.mydomain.xxx/myapp.Moreover whenever i type the Public
IP address (http://xxx.yyy.zzz.aaa) instead of
events.mydomain.xxx should also redirect to
  http://events.mydomain.xxx/myapp.

Any ideas how I might do this with apache tomcat would be very helpful
and appreciated.

Thank you in advance.

See Michel's response for redirection. If you want IP - hostname
switching, set up a rule that looks for a non-preferred Host header
and issues a redirect.

 Subject: Tomcat url redirection

 I want http://events.mydomain.xxx/ to
 go to http://events.mydomain.xxx/myapp.

Then name your webapp ROOT (case sensitive, even on Windows), not myapp, just 
as the Tomcat doc says to do.

 Moreover whenever i type the Public
 IP address (http://xxx.yyy.zzz.aaa) instead of
 events.mydomain.xxx should also redirect to
 http://events.mydomain.xxx/myapp.

That will happen automatically if events.mydomain.xxx and xxx.yyy.zzz.aaa both 
map to an IP address on the server on which Tomcat runs, *and* you have Tomcat 
listening on address 0.0.0.0 (the default), *and* you rename your app to ROOT, 
as noted above.

No rewrite filters are required if you set things up properly.

Re: HTTPConnector url redirection

[David Smith]

Just as a thought, but I've seen on occasion where Firefox in particular 
will offer up cached content when something goes haywire with the 
request.  As a test, when you drop the s from https (leaving the port 
number on the end), try to reload w/ the shift key down to force your 
browser to drop cached content in favor of fresh material.  I'm willing 
to bet it'll just give you garbage because the server will offer up a 
SSL handshake and the browser will accept it as an html response.


Now if your URLs didn't have the port numbers in them (tomcat using port 
80 for http and 443 for https) and you dropped the s from https, the 
browser would connect on port 80 instead of 443 and the redirection 
would happen again the way you are expecting.

Are you sure? Trying to get your web browser to connect using HTTP to a
server expecting HTTPS should not even be able to make a connection,
much less give you broken pages.

Can you double-check all URLs and be very careful about copying and

HTTPConnector url redirection

[raveendra]

Hi all,

I am want to run my entire application on https which is developed using
struts2.So i configured my server.xml and web.xml as shown below.

server.xml
   Connector port=8080 protocol=HTTP/1.1
   maxThreads=150 connectionTimeout=2
   redirectPort=8443 /

 Connector  port=8443 protocol=HTTP/1.1
  minSpareThreads=5 maxSpareThreads=75
  enableLookups=true disableUploadTimeout=true
  acceptCount=100 maxThreads=200
  scheme=https secure=true SSLEnabled=true
  keystoreFile=C:/Tomcat 6.0/conf/airo/.keystore
keystorePass=mypassword
  clientAuth=false sslProtocol=SSL/

Connector port=8009 protocol=AJP/1.3 redirectPort=8443 /

web.xml--

web-resource-nameama/web-resource-name
url-pattern/*/url-pattern
/web-resource-collection
user-data-constraint
transport-guaranteeCONFIDENTIAL/transport-guarantee
/user-data-constraint
/security-constraint

when i type url http://localhost:8080/myapp/start.action it is getting
redirected to https://localhost:8443/myapp/start.action.
But after accepting the certificate and loading the page.If i change my url
to http://localhost:8443/myapp/start.action just by removing 's' it is
loading the pages
with some GUI errors and after traversing couple of pages it is logging
out.I don't want it to happen.

When user remove 's' from url i want to redirect to same url with
https.Suppose if they remove 's' and it is
http://localhost:8080/myapp/start.action and load the page
i want it to redirected to https://localhost:8080/myapp/start.action.

If you are using apache, you should check the RedirectMatch directive.
You can use it to send redirects for certain regular expressions, and
use back-references for the redirected URL. I think this is exactly what
you want.

Melanie are you using FreeBSD or OpenBSD? I am going back a bit but I 
remember using Zeus on OpenBSD.


The way I set up clustering recently was through a workers.properties file 
which I stored in the apache/conf subdirectory. To start with you have to 
make sure all the prerequisites are in place. If you are using a version of 
Apache that supports it you need to DSO the mod_jk module into this (if you 
haven't done this already) with 
./configure --with-apxs=/usr/local/apache/bin/apxs. This won't work unless 
you have mod_ssl installed !make sure the version you have supports it!. For 
example if you are using an APACI version, you may face problems. If you do 
have mod_ssl installed and are witnessing problems note the error whilst 
trying to launch Apache. I witnessed numerous errors whilst trying to build 
1.3.39, 1.3.4, 2.0.x 2.2.x this way.

Hello
Actually I was able to define a rewrite rule in
apache:

RewriteRule ^/(.*web:jar.*) http://zeus:8086/src/$1
[R=301,L]

now
http://zeus/web:jar:001
redirects to
http://zeus:8086/src/web:jar:001

But if I tried to change the flag to P (proxy) in
httpd.conf
the apache error file gives:
[Thu Mar 27 17:18:58 2008] [error] [client
172.21.194.71] File does not exist:
/usr/local/apache2/htdocs/src, referer:
http://zeus/web:jar:001

the tomcat gives:

Your request is: http://zeus:8086/src/web:jar:001
Patj info is: web:jar:001
Session (1A578677550D1A75793540B152A8D6B6) has been
added to the list of valid Sessions
MY path info in treeview is: web:jar:001


I suspect I should something on tomcat to all this
operation. right?

I am using Solaris 10 - apache 2.2.4 and tomcat 6

Re: RES: url redirection

[ChrisS]

I worked with Solaris 10's apache and found that I had to download the 
apache source code eventually and rebuild it myself. I found a few bugs in 
2.2.8's configure scripts, what I am using now but I got it to work, if you 
are up for it I could help out!


I never used the P proxy flag in httpd.conf, I used jk_mod.1.2.6 (but this 
is jk_mod.1.2.7 really) then to get apache to communicate with the tomcat 
nodes I set up a worker file included it in httpd.conf, that with the jk_mod 
included in httpd's module section and I was accessing Tomcat through two 
worker ports set up in apache. Is this what you are trying to do?

Aah, mod_rewrite: the chainsaw of httpd configuration. I personally
think RedirectMatch is a lot cleaner. mod_rewrite is very heavy (because
it can do so many different things).

But hey... whatever works.

We should get terminology straight:

- redirect: change the URL and sent a 30X response back to the browser, 
indicating that the browser should instead make a new request to this 
changed URL. Browsers will handle redirects automatically, but the new 
URL will be visible to the users (and get used in bookmarks etc.)


- rewrite: internally rewrite a URL during processing without making the 
client aware of this.


- forward (in the sense of a reverse proxy): sending a request received 
by a server to another server and returning the response gotten from 
that server back to the client.


Caution: mod_rewrite can do redirect and rewrite and also interacts with 
forwarding.


I guess what you want is a combination of rewrite and forward: The 
client uses a URL which does not exist on the final server and you want 
to use an intermediate server to change this URL (rewrite) to the one 
known on the final server, sending the resulting request there and 
returning the final response back to the client.


The components you perfer to do this with are Tomcat as the final server 
(backend) and Apache httpd to rewrite and forward.


You can do the forwarding either with mod_jk or mod_proxy. You should 
have a working forwarding before getting into the rewrite business.


To do the rewrite, you use a RewriteRule with mod_rewrite and you need 
to add the pass through PT flag to let further modules (in the case of 
mod_jk) participate in request processing. The flag is important.


See passthrough in http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html.

Re: RES: url redirection

[ChrisS]

Ok so if you are using Two Tomcat nodes and you want to redirect to each of 
the Nodes in question through an Apache rewrite rule and give the 
transparency of the same URL. I am not sure you can do this


1. Are you doing this to load balance between the Two Tomcat instances.
2. You aren't bothered about loadbalancing between the Two Tomcat Nodes.

Either way I can only see that by using a different URL is your binding.
To give true transparency of URL(sameness), wouldn't it just be better to 
Loadbalance?


I would start by downloading the latest version of Apache 2.2.8. You may 
need to download Sun Studio 11 but hold fire on this. Lemme spark up the 
Solaris box, to remember the steps. The proxy through mod_jk is highly 
recommended on the sites I have researched I downloaded this version 1.2.26.


There was an issue with the Global Zone and the local zone using header 
files so Sun Studio 11 could be required, again it may not, Sun Studio 12 is 
beautiful it picks out weaknesses in the code itself. GNU Make should do the 
trick, so once everything is in place. Then comes the build, which I wrapped 
around the installation i.e path variables.


We could opt for the quicker option, if it works that is. Meaning I give you 
the mod_jk module ready compiled and you include it in your modules/libexec 
subdirectory.

I want to reference these images aswell with the '.' operator but iam

Hello,

After spending long time understanding this project i still have no 
clue.


All logic is contained in one file, testpage.jsp. Despite of the size 
of the application, this file is a relatively small file. It was 
possible to achieve through the Window Component Framework (WCF). 
This framework is a set of tags, which enables developing short 
application code based on JSP.


I have problem understanding the testpage.jsp and modifing it. Please 
find the snippet of the page souce of testpage.jsp, and the code of 
testpage.jsp respectively

take a look into your access-logs for a 404-error. then you should see the

Hello,

After spending long time understanding this project i still have no clue.

All logic is contained in one file, testpage.jsp. Despite of the size of 
the application, this file is a relatively small file. It was possible 
to achieve through the Window Component Framework (WCF). This framework 
is a set of tags, which enables developing short application code based 
on JSP.


I have problem understanding the testpage.jsp and modifing it. Please 
find the snippet of the page souce of testpage.jsp, and the code of

Re: URL Redirection

Why is renaming a webapp to ROOT the worst solution?  It's a perfectly 
acceptable solution when you want to access your webapp from the top 
level and the default ROOT is just a placeholder anyway.

Re: URL Redirection

I see the gif image is the only one referenced using the '.' current 
directory operator.  I've found it better to code image urls as 
${pageContext.request.contextPath}/images/zapisz.gif.  This will 
render the full path relative to the site and will also change 
automatically as the webapp's context path changes.

Re: URL Redirection

[Gregor Schneider]

Hi David,

assuming the client gets his software delivered from different vendors, one
day changes his mind to make another app his default application, then what?
rename everything over again?

The best solution is, leave the web-app it's name and forward with a
index.jsp inside the ROOT-context to the required app since changing this
file is way easier than renaming the wep-apps.

Besides, if it's a real-world-app, I suggest having Apache HTTP in front so
that you can also use all those feature Tomcat lags, like url-rwriting etc.

Just my 0.02 €

Re: URL Redirection

[David Smith]

Renaming everything is a very simple operation.  If the webapp is 
constructed correctly it should operate regardless of context path and 
make adjustments as necessary.  At most, some links between webapps will 
have to be updated to reflect the adjustments in path.


I also can't recommend Apache httpd in front unless the site is a mixed 
bag of technology -- perl, php, java, user client based html authoring, 
etc., ...


All I can say is I have a different opinion on this point.

exactly, and you can save the time updating them

well, most systems in the wild use at least a mix of html and some dynamic
components (most of them java-based).
having this situation, it's kinda awkward with tomcat alone.

just to give you an example:

try to change the headers of static html (i.e. caching-directive) to improve
the performance of you web-app: with tomcat, you'll need to write some valve
which adjusts the headers accordingly, since afaik there is no possibility
to change them using some config-files in tomcat. same goes for url-rwriting
etc. here, apache in the frontend comes in handy. besides, from my own
experiences i figure that serving static content via apache http performs
slightly *cough* better than serving them via tomcat.

however, i think apache http PLUS tomcat for dynamic content is a great
combination which is likely to satisfy 99% of anyone's requirements.

anyways, getting off topic here, and your oppinion is very much appreciated
- as always ;)

Typing the index.jsp-part should be unneccessary anyway. At least Tomcat 5.5 
contains an entry defining index.jsp as a welcome-file in the default 
server-wide conf/web.xml.
If you want to access your webapp without the need for it's name being present 
in the URL you could make it the ROOT context - as already suggested. Or you 
could create an index.jsp (or whatever you want to map as a welcome-file) in 
the ROOT webapp that does a redirect to your actual context.

You certainly don't need apache, but you do need to read the servlet
spec about welcome files and forwarding. :-)

Also, if the originating URL is the root of your site, where is the value

URL Redirection in tomcat

[santhoshs]

Hi Everybody,

Am using Tomcat 5.0 . My requirement is to redirect the URL
http://username.mysite.com; to
http://username.site.com/application.do?login_name=username;. The URL
should be nice URL , in the sense the New URL should not be reflected in the
address bar.

My Question is whether should i use apache for this redirection or can i
achieve this using tomcat itself ? If so what should I do to achieve this ?

Thanks and Regards, 
Santhosh
