Keep session alive forever as stackoverflow

Question

I need to keep the session live unless until the user clicks logout in my asp.net mvc(C#) application. When the user closes the browser and opens again, the session should continue with the values. I am trying to implement as in stackoverflow. Any ideas/suggestions?

Accepted Answer

You say you want to keep the session alive "as in StackOverflow."... StackOverflow, like most secure sites, does not keep sessions alive indefinitely. It uses cookies to "remember" the login.
