[users@httpd] Apache rewrite rule with hungarian character set
Hi, I am trying to configure a rewrite rule in Apache which runs on Linux server, the Apache instance has multiple virtual host one of the site runs for Hungary. While the user requested for a rewrite rule with Hungarian character set which is appearing ok in browser, however when I try to create rewrite rule which interprets the hungarian characters into mixture of special characters. Please advice, how could I achieve this, below is an example. Hungarian Character: *Öt_jó_ok a_barátságok_ápolására* Interpreted in Linux as *..t_j.._ok a_bar..ts..gok_..pol..s..ra* OR * a_bar..ts..gok_..pol..s..ra* -- Arun J

Re: [users@httpd] REQUEST_URI multiple wildcard pattern
Thank you all once again, on assisting with this issue. The requirement was
unclear till we were asked to point all the URL that should not go to
page-not-found page to /index.php.
Now we did not have to create a negation on request_uri rather a simple
RewriteRule to point those pages to index.php.

Make sure /files does actually exist, otherwise Apache will be applying
the rewrite rule to whatever your defined ErrorDocument is, if any.
Check the documentation on httpd.apache.org for RewriteLog and
RewriteLogLevel - they can be VERY helpful. Make sure you remove those
directives when you are done, you do not want to be logging rewrites on a
live server.

However with the below rule the URI pattern with actual string even is not
working.
Like I said when I try with wget www.xyz.com/files that goes to
www.abc.com/page-not-found.
RewriteRule !^/(files|admin|user|product|go)$
http://www.abc.com/page-not-found [R=301,NC,L]
Thanks once again for helping me on this.

Hi Arunkumar
You have a list of URIs to NOT match for redirection, so begin the
pattern, as you did, with !
RewriteRule !
You then have a group of top-level directory or files to be ignored, so
you can anchor at the start of the URI:
RewriteRule !^/
Then put all your dir/file names in braces, delimited by the OR operator,
I
RewriteRule !^/(this|that)
Then follow with the URI to which everything should be directed that does
not match:
RewriteRule !^/(this|that) http://your-other-host/page-not-page.
I wasn't quite sure about your spec's use of wildcards, sometimes you have
them after an /oblique/, sometimes without, sometimes not at all. I assumed
that was a typo, and that every item should have a wildcard star. If that is
not the case, please drop me a line off-list.

PS There is a note on wildcards in ! negated patterns, and why to avoid
them:
http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule
Note
When using the NOT character to negate a pattern, you cannot include
grouped wildcard parts in that pattern. This is because, when the pattern
does NOT match (ie, the negation matches), there are no contents for the
groups. Thus, if negated patterns are used, you cannot use |$N| in the
substitution string!

This is not true. Nothing beginning with the words files, or

You do not need to terminate the pattern with a wildcard --
you have
a match at the beginning.

Round brackets are good for grouping OR clauses (produce|admin),

back-references, so you can drop a lot of those brackets. Also,
you can simply your use of the gobble-everything operator (.*)

You simply need to match a few phrases at the beginning of the
string.
So:
! If REQUEST_URI does not match
^ from the start
/ oblique
(files|admin|user|product|go) any of these phrases

[us...@httpd] Internet explorer saves Drupal Dynamic pages with ProxyPass enabled on Apache
Hi,
I have moved my site running on Drupal from with Boost enabled from one
server to another, the only difference is I have used light weight ProxyPass
Apache model in where the front end Apache running on port 80 servers static
pages.
There is another Apache running on backend with port 8080 is serving the PHP
pages from Drupal.
ProxyPassReverse / http://www.domain.com:8080/
RewriteEngine on
RewriteCond %{REQUEST_URI} !^\.(gif|png|jpg|server-status)$

With Deflate and below settings enabled. However the below settings were
exist before too.
IfModule mod_deflate.c
FilesMatch \.(js|css|gif|jpg|png)$
SetOutputFilter DEFLATE
/FilesMatch
/IfModule
SetEnvIf mime image/.* unset-cookie
Header unset Set-Cookie env=unset-cookie
Could this cause something to Internet explorer to prompt to save the page
with the message Internet explorer cannot download / from The file you are
trying to download either unavailable or server busy.
The same site working ok in Firefox.
Any thoughts ?

Hi,
I have a problem with our reverse proxy. I asked this question to the
tomcat-users mailinglist, too, but no one could help me and I am
absolutely stuck with this problem. So, I hope some of the httpd
experts here, may have an idea:
Our configuration is a Apache 2.2 web server, acting as a reverse
proxy for Tomcat 6. This is the configuration:
ServerName it.localhost.de
ProxyPass / ajp://127.0.0.1:8009/spike/
ProxyPassReverse/ ajp://127.0.0.1:8009/spike/
ProxyPassReverseCookiePath /spike /
(This is the configuration in the VirtualHost entry for port 80. There
is a second VHost for SSL with SSLProxyEngine On and SSLEngine On).
As you can see, the webapp is hosted under ContextPath /spike but
available through the proxy via /. Everything works fine, until the
webapp sends an redirect to HTTPS. This is done via SpringSecurity.
The problem is, that the ProxyPassReverse directive doesn't catch the
ContextPath and converts it, if it includes the complete address.
These are the logs from the web browser:
GET http://it.localhost.de/users/65 = 302 =
https://it.localhost.de/spike/users/65
1) Why does the ProxyPassReverse doesn't convert the /spike back to /
in https://it.localhost.de/spike/users/65? Is it because the Header
isn't relative? The protocol is still AJP and so the Proxy should know
how to convert it, right?
1a) If so, how could the webapp switch from http to https and vice
versa, when not able to send the absolute address with a new protocol?
After this, I tried to set additional ProxyPassReverse directives:
ProxyPassReverse/https://it.localhost.de/spike/
ProxyPassReverse/http://it.localhost.de/spike/
This time, the /spike/ is converted to /, but the two directives leads
to an infintive loop of redirects to
http://it.localhost.de/REQUEST-URI.
2) How can I stop this loop? or better
3) How can I configure the ProxyPassReverse correctly?
Thank you very much for any help
Timo

[us...@httpd] Apache balancer manager JVMRoute missing
Hello all, I have Apache/2.2.6 (Unix) Solaris 8 configured with 4 Tomcat instances balancing using proxy_ajp_module. I noticed that the balancer manager page does not show the JVMRoute to all other 3 Tomcat instances out of them App1 App2 are running on different machine where two other Tomcat instances running on same machine. The other behaviour I have with these Tomcat instances my application logs out users forcefully after any action triggered from the application rightafter user logged in. These behaviour is from the Tomcat instances App5_TC1 and App5_TC2 tomcat instances. I have separated those two Tomcat instances from the machine App5 now the application working fine. I have configured new balancer as i3c1test it shows the JVMRoute to one of the Tomcat only not for other. I have gone through few posts and seems there are one or two cases same as my problem as below, http://old.nabble.com/Apache-Http-sticky-session-problem.-td18877839.html LoadBalancer Status for balancer://i3c1http://10.100.106.21/balancer-manager?b=i3c1 StickySessionTimeoutFailoverAttemptsMethod JSESSIONID01 byrequests Worker URLRouteRouteRedirFactorSetStatusElectedToFrom ajp://10.100.106.23:8509http://10.100.106.21/balancer-manager?b=i3c1w=ajp://10.100.106.23:8509 app1_i3c1 10Ok1602 63K 39M ajp://10.100.106.107:8509http://10.100.106.21/balancer-manager?b=i3c1w=ajp://10.100.106.107:8509 app2_i3c1 10Ok1534 63K 37M -- LoadBalancer Status for balancer://i3c1testhttp://10.100.106.21/balancer-manager?b=i3c1test StickySessionTimeoutFailoverAttemptsMethod JSESSIONID01 byrequests Worker URLRouteRouteRedirFactorSetStatusElectedToFrom ajp://10.100.221.6:8509http://10.100.106.21/balancer-manager?b=i3c1testw=ajp://10.100.221.6:8509 10Ok1 0 0 ajp://10.100.221.6:8609http://10.100.106.21/balancer-manager?b=i3c1testw=ajp://10.100.221.6:8609 app5_i3c2 10Ok0 0 0 Please advice.

[us...@httpd] [Resolved] Apache balancer manager JVMRoute missing
I still do not know the reason why and how the routes were disappearing, however it seems the missing route is mandatory to be appended with the stickysessionid to be used for continuous session tracking. So used balancer manager page to enable it and got them back, that solved my problem.

Hi Nilesh, Thanks for your response. I have already checked this with Load balancer support found the requests are getting sitributed eventually from Netscaler end.
