				The socketio path is "/socket.io/socket.io-client.js" || "/socketio/socketio-client.js" to enable buggy||working 
				client-to-client communications.  The socketio interface is established when the server does a 
				require( "socketio" || "socket.io" ) to create its endpoints at "/socketio" || "/socket.io", and when the 
				client imports its socketio via a <script src=socketio> tag.  When sockets are not being supported, 
				the server provides socketio = "/socketio/nosockets.js".
