Javascript Web Workers: Chrome 5 Now Supports Complex Messages

After updating to Chrome 5 (specifically 5.0.375.55) last night I immediately ran some tests to see if the Web Worker API had been updated to support postMessage() arguments of types other than string.

Turns out, it had.

postMessage is an HTML5 spec to help various windows (of different origins) to communicate with each other.

Details about the spec are here: https://developer.mozilla.org/en/DOM/window.postMessage

This is good news for sending machine readable messages between frames :)

Cross-domain Ajax with Cross-Origin Resource Sharing | NCZOnline

A couple of years ago, web developers were banging their head against the first wall in Ajax: the same-origin policy. While we marveled at the giant step forward enabled by cross-browser support for the XMLHttpRequest object, we quickly bemoaned the fact that there was no way to make a request to a different domain from JavaScript. Everyone setup proxies on their web sites, which was the onset of a new host of open redirect problems, as a way to get around the restriction. Although developers were working around this limitation using server-side proxies as well as other techniques, the community outcry was around allowing native cross-domain Ajax requests. A lot of people are unaware that almost all browsers (Internet Explorer 8+, Firefox 3.5+, Safari 4+, and Chrome) presently support cross-domain Ajax via a protocol called Cross-Origin Resource Sharing.

This is a really solid introduction to CORS (Cross-Origin Resource Sharing) which is currently implemented in FF 3.5+, Safari 4+, Chrome 4+, and IE8+.
