Could you use ViewState instead of SessionState?

Update:

Or perhaps a combination of ViewState and SessionState.

Here's an example sequence:

• On Page 1, user chooses "Red". Value is stored in SessionState.
• User navigates to Page 2. Value is read from SessionState and stored in ViewState of Page 2.
• User opens a second Page 1 in a new tab and chooses "Blue". Value is stored in SessionState, so "Red" is replaced with "Blue".
• User navigates to Page 2. Again, value is read from SessionState and stored in ViewState.
• User returns to original Page 2 (the one on the first tab) and performs a PostBack. Value is read from ViewState. Value is still "Red".
• User returns to second Page 2 (the one of the second tab) and performs a PostBack. Value is read from ViewState. Value is still "Blue".

In other words, use SessionState for transitions between pages. Use ViewState for PostBacks of same page.

Does that help?
