Hi, Because the ports are different, that qualifies as a cross-origin call, and cross-origin calls are essentially disallowed because of the Same Origin Policy[1].
You have a couple of options, both of which require specific support on the server: * You could have your web service support JSON-P[2], which works cross- origin. * If you're willing to limit use of your page to modern browsers and do some fiddling for IE8 and above (IE7 and below won't work), you could use the new Cross-Origin Resource Sharing standard[3]. This is a new standard that allows cross-origin calls if the server authorizes them. It's supported in modern browsers, although in IE you have to use the special `XDomainRequest` object rather than the usual `XMLHttpRequest` object used by Prototype's ajax stuff. (Other browsers, like Firefox and Chrome, support CORS via `XMLHttpRequest`.)
