WebGL port sharing issue

I realize that it isn't possible to share a port, however there should be some kind of process dispatcher that allows a browser to connect to a port, but get redirected to the specific port. 

This will affect creator as well. I was just trying out the new WebGL stuff, the app crashes if there is already an application instance on that port. 

Instead there should be a server set up on the port, which the browser is directed to, then that server issues a 302 moved temporarily message to direct the browser to the port the application is actually on. QtCreator would have to start this service first, then each request would spawn a copy of the latest binary. 

QtCreator  would then be able to work pretty much as it does now. I'm putting this under Qt because this same service would serve sessions in a multi-session scenario, so it should be part of Qt proper.
