PHP Advent 2011: Cross-Origin Ajax with CORS
I've had the honor of writing for this year's PHP Advent, blessing you all about Cross-Origin Requests with CORS:
There's no doubt that Ajax is one of the most exciting, useful, and necessary web technologies available to front-end developers. Unfortunately, it's also one of the most restrictive — especially when it comes to gathering content from other domains. Web developers are nothing if not persistent, so we've come up with a variety of ways to get around cross-origin restrictions, including JSONP, server-side proxies made with PHP, ProxyPass proxying, Flash transports, creative iFrame uses, and more. What many developers don't know is that there's a W3C specification called Cross-Origin Resource Sharing, or CORS, which provides a standard for cross-origin Ajax requests with minimal hassle.
That's my Christmas gift to you all!

The HTML

The jQuery homepage has a pretty suave tooltip-like effect as seen below:
Here's how to accomplish this same effect using MooTools.
The XHTML

The CSS
The above CSS has been slightly modified to match the CSS rules already...
The link to your post isn’t working ;) Nice article BTW, but 10 seconds too late! I just figured out that this should solve my problem with the help of our friend Google :( Nice to read that this is the way things will work for sure.
Hi David, can this this hide the httprequest referrer??
