[users@httpd] Question about Mod-proxy
Hello,
I have setup the mod proxy work with my application using the configuration
below.
When I enter a url such as http://host/myapp/ the proxy works correctly.
The target application comes up through the proxy
However, If I change url to:
http://host/myapp
(without the trailing slash), the proxy request fails.
I notice on the browser that it shows the URL of the target application (
http://172.17.2.114:7070/myapp) instead the url through the proxy -
http://hostname/myapp.
Any thoughts on what I need to change in my configuration to make this work
without the trailing slash?
thanks
suneet

Re: [users@httpd] Mod-ReWrite
I tried to add another parameter to the query string and now the different
parameters are getting merged together
I am not sure if my error is in the RewriteCond or in the ReWriteRule. Any
ideas?
URL -> http://localhost/test_rpc/header.jsp?tkn=xyz&userid=mylogin
HEADERS PASSED:
tkn: xyz;var2:mylogin
userid: (null)
RewriteCond %{QUERY_STRING} tkn=(.*)&userid=(.*)
RewriteRule ^/test_rpc - [E=var1:%1;var2:%2]
RequestHeader append tkn %{var1}e
RequestHeader append userid %{var2}e

Re: [users@httpd] Mod-ReWrite
Hi,
thanks very much for your help with this. I am a bit unclear in how
information is assigned to variables and how they can be passed from one
directive to another.
I made the change that you described below. Now the tkn header is coming in
as null. Have I made an error in assigning the tkn to var1?
URL -> http://localhost/test_rpc/header.jsp?tkn=abc
Header value -> tkn: (null)
RewriteCond %{QUERY_STRING} tkn=(.*)
RewriteRule ^/test_rpc/$ [E=var1:%1]
RequestHeader append tkn %{var1}e
Thanks for your help

Re: [users@httpd] Mod-ReWrite
Hi,
i am still having some problem with getting this to work. I am not getting
the value that is in the query string to appear in the header.
Any ideas on what I am doing wrong?
I have the following url:
http://localhost/test_rpc/header.jsp?tkn=abc
In my httpd.conf I added the following:
RewriteEngine on
Options +FollowSymLinks
RewriteCond %{QUERY_STRING} tkn=(.*)
RewriteRule ^/test_rpc/$ [E=var1:%1]
RequestHeader append tkn var1
In my test, the Header "tkn" shows up with a value of "var1", instead of
"abc" which is on the query string.
Thanks in advance for your help

Thanks Igor. Would you be able to point me to an example? I dont fully understand how I can configure this to take a parameter of the query string and then set a variable as a header. thanks for your help On Tue, Sep 20, 2011 at 6:29 PM, Igor Cicimov wrote: > Use mod_rewrite to set variable and then set that var as header. > On Sep 21, 2011 7:32 AM, "Suneet Shah" wrote: > > Hello, > > > > I had a question about Mod-Proxy and Mod_headers > > > > 1) Is it possible to take a values that are on a query string and pass > them > > as headers?

[users@httpd] Mod-Proxy and Mod-Headers
Hello, I had a question about Mod-Proxy and Mod_headers 1) Is it possible to take a values that are on a query string and pass them as headers? If so how? For example, if I have: http://host/myap?userid=abc&role=myrole I would like to take the values in the query string and pass them as headers to the app that I am proying to 2) I would like to pass the above headers or query string parameters on every request. How can I do this? Is there a way to put these values in session have have them passed as headers every time? If there is a better appraoch for the above, please let me know. thanks in advance for your help suneet

[users@httpd] Question About Mod-Headers
hello, I am using Mod-Headers to pass some customer headers to one of our applications. I am passing some customer header using the directive below. However I am noticing that the module converts the header value to be lower case. The application that we are passing these to is checking the header name in a case sensitive manner. Is there a way to control the case of these header values as they are passed to the target application? RequestHeader append Userid "my_header_value" thanks for your help
