i added remove(Page) to session and renamed expireNewerThan(Page) to removeNewerThan(Page) because expire is confusing here given the stale boolean and all... remove is what these methods do.
anyway, this should solve your problem. just call Session.remove(Page) on your popup when it closes.

I agree that users should have the possibility to discard pages from the session that are not important for further application flow. ExpireNewerThan would not work here, as it will also expire the popups that were opened later than the one the current popup.
The other way around would be to have pages that will allways sit in the session (e.g. kind of static pages), but I see much more problems with this than providing users a means to expire one specific page in the session.
So, I'm +1 for adding an expirePage method in session.

Hi,
I have the following situation:
1 “Main” Page which can spawn multiple popup’s.
Each popup is a new Page in a new browser window.
Each popup ultimately goes to a new Page which renders html that will close the popup (call it the ClosePopupPage).
Upon closing the popup the main page is refreshed through javascript.
All works fine until I reach the session limit of 10 Pages.
With 1 Main Page this means I can open and close 4 popup’s without problems. I can even open the 5^th , but when I close the 5^th popup the main Page is kicked from the session to make room for another ClosePopupPage.
When that page is loaded by the browser it attempts to refresh the main page, but since it no longer is in the session, I get a page expired message.
Now I could change my code to reuse Pages and or use less Pages or increase the Page cache size but this will only postpone the inevitable.
A method in Session allowing me to “expire” a Page would IMO be the correct solution.
That way I could remove all Pages related to a popup when I close the popup, this way the cache never gets full.
