If I'm hosting a site in windows azure with an out of proc session provider and perform a VIP swap, will the session persist through the VIP swap since the session is being provided out of process?
I will come back and answer the question after I perform a test but I'm pretty sure someone will have the answer here asap and azure deployments take a while.
I see no reason why it shouldn't work.
It should be no different than hitting different instances that are part of the same deploy.
