Re: session variables in struts

["Scott P. Smith" <ssmith@scott-smith.com>]

I solved this problem once by having two types of session objects: permanent
and temporary.

All my permanent session objects had names that started with an underscore
'_'.  My wizard session objects, like the one you specified, where temporary
session objects (without the leading underscore).

Then I had my main menu action class (I had a single action class that
proceed all main menu actions) clear all session objects whose names did not
start with an underscore.  That's basically what you are suggesting, I'm
just filling in the details for the way we implemented that approach.

There's probably a better way (there usually is), but this is what we did.
