xhr-polling doesnt work on embedded webviews (phonegap, cordova)

[max-mapper]

if you restrict the transports (on both server and client settings) to ['websocket', 'xhr-polling'] then embedded webviews using socket.io won't be able to connect and will emit the connect_failed event

Oh so setting secure: true still fails correct?

If you can get me some more debugging information that would be great.

ok, turns out socket.io assumes that if window.location.href is not the same host as the host you pass into io.connect then it should skip xhr-polling. you can override this behavior by monkeypatching thusly:

io.Socket.prototype.isXDomain = function(){ return false; }

* it assumes that only if CORS is not supported as well (io.util.ua.hasCORS needs to be false). Which is not on Android apparently, but WebViews still have the ability to disregard the origin security model. I'm introducing an option to solve this more elegantly without the override.
