Does an IIS worker process clear session variables when it recycles?

Question

We're writing an asp.net web app on IIS 6 and are planning on storing our user login variables in a session. Will this be removed when the worker process recycles?

Answer 1

If session is stored in-proc then YES worker process recycle will remove it. Use Out-of-proc model or sql server to store session value if you want to keep it stored.

Answer 2

If you are using the default in-memory session management, the session variables will be cleared when worker process recycles

Answer 3

yes, unless you are using out of process session state.
