Agreed, that would be the cleanest way to do, but it may not always be
feasible and would need a lot of code and rework for my project.
I was just looking for something simpler.
Right now my code depends on my existing
"WrapInUserTranactionServletFilter" and i wanted to optimize server
loadby just *not* applying this filter to the
"getFromBufferAfterRedirect" request.

yep, i was misleaded because the URLs (for the event as well as the
redirectToBuffer) look quite similar.
In fact
IEventProcessorStrategy.processEvents is just called when it is a real
event-request (i.e. the first one).
So i subclass DefaultEventProcessorStrategy and start my transaction
there (only if requestTarget is instanceof
ListenerInterfaceRequestTarget or BookmarkablePageRequestTarget or
PageRequestTarget, therefore also avoiding transactions for
resource-requests).
Committing the transaction is done in a subclass of
DefaultResponseStrategy.
Just wondering what you meant by " do the open/close in
the attach en detach."?
