Chrome: Allow Cross-domain requests [OSX and Win]


During the development process of an application, we are often required to call services from domains different to the one our application is being served from, using AJAX requests.

In computing, the same-origin policy is an important concept in the web application security model. Under the policy, a web browser permits scripts contained in a first web page to access data in a second web page, but only if both web pages have the same origin.

Note From Chrome version 22+ you will get an error message that says:

You are using an unsupported command-line flag: --disable-web-security. Stability and security will suffer.

You can ignore the message as it won't affect your session.

To prove that the solution is working, open this fiddle and play around with the console open: you will get no errors.

Enjoy Chrome freedom!
