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!

![MooTools Image Preloading with Progress Bar]()
The idea of image preloading has been around since the dawn of the internet. When we didn't have all the fancy stuff we use now, we were forced to use ugly mouseover images to show dynamism. I don't think you were declared an official...
![Scrolling “Go To Top” Link Using Dojo]()
One of the most popular code snippets of posted on my blog has been the scrolling "Go To Top" link snippet. The premise of the snippet is simple: once the user scrolls an element (usually the BODY element) past a given threshold, a "Go...
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??
