Hey Alan, thanks for your answer... you know what, you are right, I don't know exactly why, but I'm not performing an HTTP GET but an HTTP OPTION. This can be related to FireFox 3.5 (see http://hacks.mozilla.org/2009/07/cross-site-xmlhttprequest-with-cors/) but even if this is the reason I have no idea on how to solve the problem...
Do you guys have any idea?
