SetEnv proxy-nokeepalive 1
ProxyPreserveHost On
RewriteCond %{REQUEST_URI} (.*\.jsp$)|(.*/servlet/.*)|(.*/workspace/.*)|(.*\.do$)

I am not able to understand that if I am able to use external redirection then what is the issues with internal proxy redirection. I am stuck up since last 1 week.
Please help me.

No you do not need to statically link mod_proxy. Loading it as a DSO is just fine.
As shown by the RewriteLog, the request is indeed proxied to mgtpdma3.rau.valmet.com:7003. If you doubt that, you can check the application server logs on mgtpdma3. I would still like to see a trace of the requests and associated responses from the moment you issue the request for /metso/login.jsp, until you receive the 404.
If you had a proxy problem I believe you would have gotten a 500, or a 502. The 404 could either come from the application server, or from Apache. In that case we would need to know which of those issue the error, and the exact URL requested. If you want help with this problem, please provide a trace or at least a relevant snippet of your access logs.

But my problem is that if I remove [P] tag then every thing works fine. so do I need to have compile version of mod_proxy.c as the manual page for apache 1.3 says but its not there at apache 2.0 manual page. I am using apache 2.0.55
Output of httpd -l shows the following
$ ./httpd -l
Compiled in modules:
core.c
worker.c
http_core.c
mod_so.c
I have the mod_proxy_http enabled too. So what could be the poblem?
