session - SessionID keeps changing in ASP.NET MVC why?

Question

I am trying to keep track of something and using the SessionID as they key to that object

However the SessionID every 2-3 reqiests changes shouldn't it remain the same?

HttpContext.Session.SessionID

Is the code I am using.

Answer 1

I've seen that happen even without MVC. If I remember correctly, ASP.NET keeps assigning new session ids until you place something into the Session variable.
