Cross-domain Ajax requests ( Using the XMLHttpRequest / ActiveX object ) are not allowed in the current standard, as per the W3C spec:

However there's 1 technique of doing ajax requests cross-domain, JSONP, by including a script tag on the page, and with a little server configuration.

jQuery supports this, but instead of responding on your server with this

{"message":"Hello World","version":"1.0"}

myCallback must be the value in the "callback" parameter you passed in the $.getJSON() function. So if I was using PHP, this would work:

echo $_GET["callback"].'({"message":"Hello World","version":"1.0"});';
