I\'m wondering, in IE & Firefox you\'re able to setup the browser, to allow cross-domain calls.
I can\'t find any option in chrome for that (actually, there are
No. Sorry.
Chrome and Firefox, however do support cross-domain requests via the W3C CORS spec (Cross Origin resource sharing) however the remote host has to enable it. If the remote host supports it explicitly then you don't have to make any changes to your XMLHttpRequest to be able to fetch the content.
