There is no reason to instantiate a new one. The manager is in charge of 
maintaining the physical connections and share then with all the clients.
So there is only one such manager started.

The only way to have this information is to inspect the Referer header of 
a request. If the browser is kind enough to fill it! Otherwise, as HTTP
