I ma starting to test a multi tenant solution, initially using url paramaters to confirm switching databases does indeed work
This works correctly.
However If i test 2 separate webapps in different tabs on browser I get the Session Key Not Known error on the second run webapp.

I note that in Harms video using host files he has no issue with Session keys

Do I need to manipulate psSessionCookieName to allow running 2 separate invocations in the one browser?
Am I missing something?
