Description

Hi

First, the full discussion and details (code and Fiddler 2 debugger snapshots) of this bug was initially discussed within recent "Using jQuery" forum submittal:

http://forum.jquery.com/topic/jquery-ajax-is-attribute-contenttype-deprecated

I think I discovered a bug in jQuery.ajax() when assigning a value other than default to property contentType, or it is a bug in Mozilla and Chrome.

Reference: http://api.jquery.com/jQuery.ajax/ , property contentType , Default: 'application/x-www-form-urlencoded; charset=UTF-8'

Assigning '''contentType: 'application/x-www-form-urlencoded; charset=UTF-8', this works fine with three browsers tested: IE9, Mozilla FireFox, and Chrome (all the latest stable versions).

However, assigning contentType: 'application/json; charset=UTF-8'''', this messes up the request body when run within Mozilla FireFox and Chrome and fails, but this same change runs perfectly fine in IE9.

Details of the Requests bodies are at the bottom of the aforementioned forum submittal.

Thank you for looking into this problem.

Based on the forum thread, it looks like the browser is doing a preflight because the content-type you provided is not the normal form-url-encoded value. Can you provide a complete test case? Is this a request to the same domain?
