Re: Can somebody tell me if there is a way to automatically inval idate a session variable?

[Savas Alparslan (Garanti Teknoloji)]

I think we must stress the word "automatic" in the question. We're facing
the same problem: You store many state variables in the session and then
user suddenly clicks to a unrelated link, breaking the operation sequence
and there're many variables left in the Session.

I don't think there's an automatic way to clear variables but, one solution
may be use hidden form fields instead of using session to store operation
specific variables. Another solution maybe to encapsulate operation specific
variables in an object, and store this in the session. And in any way you
explore that user begins a new operation sequence, clear this object. The
disadvantage of the first one is your variables are exposed in hidden
fields, the disadvantage of the second one is when the user chooses "Open in
Window"
