Fixed: CFHTTPRequest now accepts the withCredentials property
Fixed: CFHTTPRequest now accepts the withCredentials property

From the original PR:

Currently, CPURLConnection has no way to access the withCredential
property of an XMLHTTPRequest, meaning we can't utilize cross-domain
calls using CORS in our applications.

This commit adds the withCredentials property to CFHTTPRequest.
