Our application embeds SAS generated html
String with
Java generated header and footer for the application report.
In our report pages, there are "Back" buttons which use history.back() to
call the same process on the server.
Clients can tolerate waiting a long time after pressing the "generate report" button for the report,
but cannot tolerate the "Back" button taking the same time as "generate report" button.
So I wander if the application can cache the SAS returned String or cache the whole report page
Some where only for "Back" button being pressed.
I do not want cache the html String in Session because I do not know how big the page is returned
by SAS.
