sharing data between two different apache modules

[Atanu <atanu.das@xxxxxxxxx>]

Hey folks,

I need the assistance from you on a problem with mod_perl and mod_proxy. Please help.

This is what I am trying or aiming to do.

I have an Apache 2.0 server running mod_proxy with reverse proxy. So all the request from http://www.foo.com gets proxied to http://baa.com. So far so good and this was a piece of cake. I want to now try out something else.

- The user will still type http://foo.com. This time a mod_proxy handler will display a login page. In fact this my own authentication handler written in mod_perl. It authenticates using a back end system by accepting username and password from the login page.

- If authentication is NOT successful, it displays the login page again.

- But if the authentication is successful a session cookie is created.

- The mod_perl login handler job should end there.

I want the mod_proxy to ProxyPass to the url in the following format

http://bar.com/bar.pl?sid=APACHE_SESSION&u=UserName 

if the authentication is a success and for all subsequent request should retain the session as I do not want to show the login page to the the user again.

How should I approach the problem especially reading data from the mod_perl authentication handler and passing it as a query parameter for the proxy URL?

Anticipating a "hint" solution from anybody!!

Thanks a lot,

Atanu
