Question

Is it possible to set the timeout of a session variable to say one hour programatically.

How would I go about in doing this?

The reason I am asking is because of storing the contents of an arraylist into a session variable and these contents needs to be available way beyond the current timeout of the session variable.

Answer 1

No, because the timeout works for the entire session.

But you can set an artificial expiration time for the session item and increase the session max idle time/timeout. Thus you can store an object like this:

public class SessionValue 
{
      public object Value { get;set; }
      public DateTimeOffset ExpiresOn { get;set; }
}

And whenever you get the whole session item, you can check if it’s still valid or it has expired.
