javascript - Cross domain jQuery ajax call with credentials

Question

I've followed the following steps:

1. Get the server to allow cross domain calls (with all the headers and stuff) This works
2. Test the server with some cross domain calls This works
3. Get the server to force a certificate This works
4. Go to a file on the server with a browser, choose the right certificate and see the file Still works
   Now we get to the nice part
5. Combine the cross domain calls with the certificate <-- this does not work

Problem

I am getting the certificate request from the browser, but when I select the same certificate as I do when using the browser, the call is made but I get a 403 Forbidden.

Code

$.ajax({
     type: "POST",
     xhrFields: {withCredentials: true},
     dataType: "xml",
     contentType: "text/xml; charset="utf-8"",
     url: "https://www.myOtherServer.com/testfile.asp",
});

Any ideas?

Edit

The Access-Control-Allow-Credentials: true and the Access-Control-Allow-Origin are properly configured.

Additional information

I'm starting to think that it has something to do with the content type. When I change it to "text/html" I get a 415 error, but I do really need to send xml because it is a SOAP server.

Answer 1

My best guess is that this is a problem not with your Javascript but with your CORS configuration. Did you set up your server with the Access-Control-Allow-Credentials: true header? http://www.w3.org/TR/cors/#access-control-allow-credentials-response-header

Also note that, even when the allow-credentials header is set, the browser will not allow responses to credentialed requests if Access-Control-Allow-Origin is *, according to these docs: https://developer.mozilla.org/en-US/docs/HTTP/Access_control_CORS?redirectlocale=en-US&redirectslug=HTTP_access_control#Requests_with_credentials.

Edit: Since the OP has the CORS headers set up properly, the problem seems to be that the server is rejecting OPTIONS requests with a 403 status code. OPTIONS requests (known as the "preflight request") are sent before certain cross-domain requests (such as POSTs with application/xml content types), to allow the server to notify the browser of what types of requests are allowed. Since the browser doesn't see the 200 response that it expects from the OPTIONS request, it doesn't fire the actual POST request.
