Description

Using $.ajaxPrefilter in Cross-origin resource sharing leads to 'parsererror'.

I'm using ajaxPrefilter to prepend server address to url before firing request. Request is send to proper url (as expected) but parser fails with textStatus 'parsererror' and errorThrown 'No conversion from json to domain.name/api/url (this is the full URL that is requested).

Here's how to reproduce:

$.ajaxPrefilter(function( options, originalOptions, jqXHR ){
  options.url = 'http://updates.html5rocks.com' + options.url;
});

$.ajax({
  type: 'GET',
  url: '/2012/09/Live-Web-Audio-Input-Enabled',
  success: function() {
    console.log('success');
  },
  error: function(jqXHR, textStatus, errorThrown) {
    console.log('textStatus: ' + textStatus);
    console.log('errorThrown: ' + errorThrown);
  }
});

Could you provide a reduced test case for this? Not a jsfiddle since "Origin http://fiddle.jshell.net is not allowed by Access-Control-Allow-Origin.", but a simplified example on your server.

From what I can guess, you most probably set the dataType option of the request to "domain.name/api/url" somewhere. So there's something going on outside of this prefilter or the prefilter is more complex than what you put here.
