Hi Henrik Thx.. Finally its working fine. Both servers are behind reverse proxy and can be accessed with resepective URLs Now the original issue:: One of the servers behind reverse proxy is a domino server. 1. When user types 'test.webmail.com', reverse proxy gets the authentication page from the internal domino server (1.1.1.1). 2. User types in User name and password 3. Domino tries to redirect but nothing changes in the user window. It just takes credentials from user and returns the same authentication page Without the reverse proxy when same process is completed, the URL changes in user browser as the domino server redirects it to internal server(1.1.1.2) where .nsf mailbox is stored. I tried putting the mailbox (1.1.1.2) server also behind reverse proxy but nothing changes. I guess something more to be added to squid.conf Sameer Joshi -----Original Message----- From: "Henrik Nordstrom" <henrik@xxxxxxxxxxxxxxxxxxx> Sent: Mon, January 8, 2007 8:29 pm To: sameer.joshi@xxxxxxxxxxxx Cc: squid-users@xxxxxxxxxxxxxxx Subject: Re: Redirection by backend server mån 2007-01-08 klockan 18:57 +0530 skrev Sameer Joshi: > www.abc.com :Is the url given to users to access the server from internet > (this is not configured on webserver. its only in squid.conf) You better configure this on the web server as well if it is using the Host header.. It is possible to run with different domains internally and externally some times by using a redirector to rewrite the URL while it is forwarded, but there is a lot of situations where the internal domain of the web server will "leak" and cause problems so it can not be recommended.
