Hi Nicklas,
my first idea was to lookup the connection from pool and store it within the session.
But what about browser or network crash :( , maybe the session timeout must cleanup.
I'm unsure whether this is a good idea.
Do you can use one connection parallel with two session? or must it an exclusive usage?
How the temporary tables handled, e.g. deleted if the session crash?
Also you might open lots of connections in parallel.
