That sounds like it shouldn't be too difficult to test. Have your upstream
refer to two different nginx server blocks, and be able to identify in the
logs which server was used.

Then send a request to vhost1, to vhost2, to vhost1, and to vhost1
again. Did the first two to vhost1 go to the same upstream? And did the
last to vhost1 go to the other upstream?

I'll be interested in seeing your conclusions.

Good luck with it,
