I use seaside exclusively in VWNC 7.3.

I usually run:
MyApplication initialize.
WASession allInstances do: [ : item | item expire].

To try and expire the 15-20 sessions that are hanging around after time spent developing.
Sometimes this works fine, other times it fails. Which makes me wonder if there isnt something else under the hood that needs to be looked into.

I'll try the fixes posed in this thread tonite and see what results I get.

Im in favor of trying to expire sessions everytime a new session is created unless we can see the checking process is expensive.

meanwhile keep up the good work in porting to VW.
Jon.
