We are using Apache/2.2.3 and need the URL redirection as follows



m.test.com/prodtest/?v=TT78UUU             (User Request)
               |
               |
               |
m.latest.com/test.new/1f_landing/?v=TT78UUU                             (Processed as )
               |
               |
               |
m.test.com/prodtest/?v=TT78UUU           (output domain and url should remain same)

Note : We don't have any prodtest folder
TT78UUU   is a aplha numeric variable

Thanks,
Ramesh

Change alias
Alias /prodtest /some/path/to/directory
to
Alias /prodtest /some/new/path/to/directory

This is part of your configuration file it can be within httpd.conf or an individual file within the conf.d/ /etc/httpd/conf.d /etc/apache2/conf.d.
Depending on the version/distribution of linux you use.
once you make the change, you need to issue a graceful/reload to apache
/etc/init.d/httpd
/etc/init.d/apache
/etc/init.d/apache2
Depending on which is available to you.

Hi Arnold,

I'm sorry.

I missed to update that the application is running on Tomcat and Apache is on the front.
So the requests comes to Apache and it forwards it to tomcat.

We are using tomcat6.

You should then reconfigure tomcat to now use the other directory.
or rename the current directory where tomcat is answering from to the one with the newer data.
A redirect by its nature alters the URL that is displayed in the browser since it is the browser that initiates the connection back using the newly provided URl in the redirect response.

Once you rewrite the URL it is sent to the browser saying, you wanted X, but it has moved to y.
The browser then initiates a new request for Y.

To do what you ask, you have to make changes on your tomcat server to serve the data from test.new when the request comes from /prodtest/.

You should not be latering any configuration on the apache side, but you should adjust the parameters on the tomcat side.

Look at the  configuration.

copy the old stuff so you have a backup.
Copy the new stuff in place of the old stuff.

Look at how your /etc/httpd/conf.d/tomcat.conf

Look at how where and how your existing /prodtest is defined within the apache configuation.

This is my apache virtual conf file :

<VirtualHost dev02:80>
   ServerName a.test.com
   ServerAlias m.test.com
   ErrorLog /var/log/httpd/a.error.log
   CustomLog /var/log/httpd/a.log combined

   SetEnv force-proxy-request-1.0 1
   SetEnv proxy-nokeepalive 1


        RewriteEngine On
        RewriteLog /var/log/httpd/rewrite.log
        RewriteLogLevel 9

        RewriteCond %{REQUEST_FILENAME}   !-s
        RewriteRule prodtest/1f_landing/ test.new/1f_landing/$1 [R,NC,L]

   ProxyRequests Off
   ProxyPreserveHost On

   <Proxy *>
     AddDefaultCharset Off
     Order deny,allow
     Allow from all
   </Proxy>

   ProxyPass / http://test02:8086/
   ProxyPassReverse / http://test02:8086/
</VirtualHost>

And now when i'm hitting

http://m.test.com/prodtest/1f_landing/?v=TT78UUU

i'm geting

http://m.test.com/test.new/1f_landing/?v=TT78UUU

I just want to replace test.new with prodtest.

Proxy pass is what passes the query to tomcat.
Your apache cofiguration suggest that it is setup as a reverse proxy to the tomcat.

rename the prodtest to prodtest.old and test.new to prodtest.


Look at the configuration of your tomcat/catalina.conf or something like that.

You should request attention for the question to have the assignment adjusted.  You can not award yourself points. You would be able to award what you view my comments are worth.
i.e. if you figured out the solution on your own, you can add what/how you came to the solution and select that post as the solution 0 points.
If other comments were helpful, you can still select your question as the answer with the others as assisting and assign the point value you think is appropriate.
