Using AJAX across domains

[coglethorpe]

I've seen "AJAX" powered services that run only with a JavaScript loaded remotely:

<script type="text/javascript" src="http://www.example.com/my.js">
</script>
​

Easy enough, but what if I want that to make a call to a server on another domain? Obviously, there are services that do that, but I'm not completely sure how, given the same origin policy.

I'd like to create a service on one domain and have my other domains use it without using iframes. I'm sure this is possible, but I can't figure out how. Examples, tutorials or anything is appreciated.

Thanks!

You can setup a local server file that redirects your request to the applicable domain.

You can do cross-domain JSON with jQuery:
Release:jQuery 1.2/Ajax - jQuery JavaScript Library

I thought about that, but I was trying to do it all in JavaScript, to avoid having to put another file on each site.

JQuery Rocks!!! I would place the file and call it a day.
