Does i need to apply Sessions in ASP.NET for log in/log out if im using SimpleMembership in MVC?

Question

I am new to web development so, do i need to implement sessions while i am using SimpleMembership as i was having problem with back button after logs out. It goes to the previous page instead of login. So I added code below in global.ascx. It works perfect now!!

Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
Response.Cache.SetNoStore();

So my query is, can i run my application without sessions in which there is Authentication of users i.e. there are user accounts and login and logout functionality is there.

You can login and logout by using default SimpleMembership functions:

For Login:

bool success = WebSecurity.Login(form["username"], form["password"], false);

For Logout:

 WebSecurity.Logout();
