Sharing server sessions per thread doesn't work when doing https to http

When running a reverse proxy with incoming https scheme and outgoing http, the share server sessions value of 2 doesn't work.

Since the https and http thread pools are separate after using the http connection it will be released to the http thread. When a new https request comes in it will look in the https threads servers session pool to make a request to the origin even though it is a http request. Of course it will fail the lookup since the ports wont match.
