RE: [Webware-discuss] how to handle expired sessions?

[Geoffrey T. <gta...@na...>]

Hmmm.  I haven't tried Webware from CVS recently, but it sounds like this
behavior has changed since Webware 0.8.  I'm pretty sure that in Webware
0.8, if you set IgnoreInvalidSession to 1 then when you call self.session(),
if the session has expired then you get a fresh, empty session with no
KeyError.

If so, then this is a bug in CVS.

Is there any chance you could try this with Webware 0.8?
