We have just recently launched a new website but on the production server the sessions go all mad. They randomly come and go as you navigate on the site. For instance, I can update the same page repeatedly and sometimes the sessionvalue (i.e. holding a login name) is there, sometimes not. I have tested on different browsers, and it's not a client browser cache problem.

On the test server this problem doesn't occur. The sessions work just fine. So, what could be the reasons for this?

hi,

if some information is not crucial then make use of query string.I was also saving the same problem.My application was hosted on two different servers(one on windows and other one on unix)through unix server we were making use of frameset and calling .net application from windows's server.On unix server sometime we don't get the session values.But at the same time it works fine on windows's server.So i think it is a server's problem.To overcome this problem I used query string.

The problem is now solved. We had 2 working processes in the application pool which caused the problem.
