Thanks for clarifying that.

Subject: [users@httpd] Reverse proxing through apache where backend server users cookie authentication


Hi Guys,
 
I am trying to use apache as my reverse proxy for my backend server which uses Cookie based
authentication.
 
I am using mod_rewrite for the proxing part and am able to come till the login page.
But am unable to login to the system. 
I suspect that it has something to do with the cookies not being reverse proxied or something.
 
I am using Apache 2..0.54 on a windows XP system.
 
Can anyone please tell me what probably could be the issue with my configuration?
 
Regards,
Rajiv.
