we are testing a e-services type system which currently relies heavily on publish/subscribe ala JMS (but not). I use threading in AOLserver with forms to initiate messages and then subscribe/check various databases etc...
So nothing complicated but working toward fully automated self documenting test procedures
just this mime issue is annoying as it doesnt always happen, just on Linux (where the servers are). I suspect something about not sending headers back but the tcl pages are just transaction pages then pass off to a adp page for output
