How to get redirect URL using an AJAX Request?

I have a problem.. in my project, i need to make an AJAX request to a URL shortener site (such as bit.ly, etc..).

My target is either I could get the redirect URL or the content of the redirected site. This far, after I tried some techniques from the web, I still cannot get the correct result.

I tried to catch the 301 HTTP response status (the default behaviour of URL shortener sites), but I found that the request never returns 301. Strangely, it returns 200.

Any idea how to solve this? Thanks a lot.. :)

According to the spec quoted in this answer a 30x header will automatically be followed and there is no way to get hold of the redirecting resource from within an Ajax call:

The same-origin request event rules are as follows:

If the response has an HTTP status code of 301, 302, 303, or 307 If the redirect violates infinite loop precautions this is a network error.

Otherwise, run these steps:

  • Set the request URL to the URL conveyed by the Location header.

  • If the XMLHttpRequest origin and the origin of request URL are same origin transparently follow the redirect while observing the same-origin request event rules.

  • Otherwise, follow the cross-origin request steps and terminate the steps for this algorithm.

You will probably need to use a server-side solution for this.
