I mocking my API using Apiary.io. But somehow I cannot read any headers from response object using angularJS. And I am sure i have at least Content-Type: application/json correctly set-up by checking in firebug. Code in Angular should read headers correctly too as i can print them when sending request to somewhere else than apiary.io...

  $http.get('').then(function(response) {  
    console.log("ok",response.headers('Content-Type'));
    },function(response){console.log("err",response);});

It all boils down to a bug in firefox: https://bugzilla.mozilla/show_bug.cgi?id=608735

For CORS request, firefox is not returning anything for req.getAllRequestHeaders(), although req.getRequestHeader('Content-Type') returns properly.

Either FF bug has to be fixed or Angular must work around it (as jQuery does) or you must go deeper and use XmlHttpRequest instance directly.

This was maybe also related, but probably not the core issue:

However, few days ago, Apiary.io was not setting Max-Age in CORS headers. Thus, if you had a minimal blueprint, you might have CORS pre-flight response cached and thus subsequent requests may be disallowed even if you added additional resources to your blueprint.

Max-Age is now set to 10 seconds, so it should work properly. However, depending on your browser, pre-flight cache might still affect you. Try purging it or test this app in another browser.
