Question

I have two applications:

• AppA in localhost:1834
• AppB in localhost:3597

An html page of AppB call a method of AppA with the following code:

jQuery.support.cors = true;
$.ajax({
    url: 'http://localhost:1834/Home/SomeAction',
    type: "GET",
    dataType: "html"
}).done(...).error(...);

AppA return an html fragment.

The code works fine with IE9 (also with type=POST, data=somejson, contenttype=”application/json”), but it doesn’t either with FF12 or with Chrome19 (Status=0, StatusText=”error”)

Is it related to cross-site scripting?

ps:

• The call to AppA works and AppA send a response with 200 status code.
• jquery 1.7.2.

Thanks.

You’re right, it is related to Same Origin Policy. Your request have to be on the same domain and the same port.
