Question

I’m calling a server site on our internal server. This domain looks like this:

http://server.domain:12345/x.html

Now, with IE this works just fine, I’m getting the data. (My problem there is that IE caches the website after the first call forever, but never mind).

Now, if I’m trying to do exactly the same in Firefox, it won’t work, the same in Google Chrome.

Firebug says this:

Chrome says this:

It seems you perform cross-domain JavaScript calls. The target server must set the Access-Control-Allow-Origin HTTP header. In your case the server http://server.domain must set a header like:

Access-Control-Allow-Origin: http://otherserver.domain

I do not know why it works for IE, it may have to do with your security domains as your just working in the intranet.
