[atmosphere.js] long-polling XDR fails to suspend in IE9

[nite23]

A following problem appears,only with Internet Explorer, and only when using cross-domain connection:

After the client calls subscribe(), and issues HTTP GET request, server closes the connection and returns a response immediately, instead of leaving it suspended.

Tested with rest-chat example, on Atmosphere 1.0.0.beta4, GlassFish 3.1.2.2, Jersey 1.9.1, Java 7

Following client settings were used:

• request.transport = 'long-polling';
• request.enableXDR = true;
• request.dropAtmosphereHeaders = true;
• request.attachHeadersAsQueryString = true;

Here is the content of issued HTTP request, and corresponding response:

GET /test?X-Atmosphere-tracking-id=0&X-Atmosphere-Framework=1.0&X-Atmosphere-Transport=long-polling&X-Cache-Date=0&Content-Type=application/json HTTP/1.1

And here is the packet trace:

Looking

OK since the suspend operation set a response of content-length == 0, IE throw an error. I've added a workaround.
