[users@httpd] Reverse proxy with response update

[FRAS Eddy RD-TECH-REN <ed...@francetelecom.com>]

Hi all,

I'm trying to have a special architecture I'm managing with my own java application for now.
The current flow is : 
1. Send a request to a reverse proxy server (java servlet on tomcat), for example : http://myreverseproxy/GO_TO_www.anotherserver.com/a_page.xml
2. The servlet fetches content from the remote host, here www.anotherserver.com/a_page.xml
3. When the servlet receives the page, it applies an XSL on the page and send the result to the client.

The flow I would like to have is the same but with Apache having the role of the reverse proxy server and remove the reverse proxy stuff from my java application.
With mod_proxy and mod_rewrite, I was able to have the content fetch from a server I specify in the URL but I really don't know if it's possible to pass the content fetched from a remote host to my java app for XSL treatment.
I had a look to mod_proxy_ajp but it seems to only allow redirecting the request to tomcat, not the response.
Is my idea unfeasible with Apache ?
