Re: Session state and multiple windows/frames

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Well, you can use separate session variables for
different sets of ViewState. But, if you are using
that much ViewState and then storing it in
session, your site quickly eat up
a ton of RAM when traffic goes up.

I'd have to see the actual page in order to
give you any useful suggestions.
