jQuery Form Plugin + Uploadify

I am using the jQuery Form Plugin to process my forms, and a json file is being returned.

The problem I am having is that when using Uploadify, instead of the jQuery Form Plugin calling the success function, the browser instead tries to download json file.

This is the case in IE8, Firefox and Chrome.

Here are headers from a form without Uploadify:

Content-Encoding gzip

Vary Accept-Encoding,User-Agent

Content-Length 42

Keep-Alive timeout=5, max=100

Connection Keep-Alive

Content-Type application/json Request

May be you should just change the Content-Type of the response which corresponds to the request's Accept header?
