Overriding Access-Control-Allow-Origin restriction in Google Chrome

I make AJAX calls to URIs which belong to a different domain. Normally in IE I am able to do this via jQuery's CORS support. But this fails in Google Chrome irrespective where CORS support is set or not.

Now I get an error saying something like:

XMLHttpRequest cannot load . Origin http://localhost:8000 is not allowed by Access-Control-Allow-Origin.

Is there a setting in Google Chrome which disables the Access-Control-Allow-Origin restriction?

There is a command-line switch which does the trick: --disable-web-security

Just call it like follows:

$ chromium-browser --disable-web-security http://localhost:8000/pages/index.html

Make sure the Chrome browser is fully closed, otherwise it will only launch a new instance and the applied option will not work.
