A component in my application is sending me a POST request via XmlHttpRequest. The request specifies a "virtual" domain (
http://loadhtml/dragdata). I successfully read the POST data in my GetResourceHandler callback, but I'm not exactly sure what to send back in response. I was simply returning NULL, but that resulted in an ERR_NAME_NOT_RESOLVED (which makes sense due to the virtual domain). What's the proper way to respond to this? I feel like I'm missing something. Everything is working correctly for my needs (as far as I can see anyway), I just want this error to go away in DevTools.
