Yes, this is a cross-domain request. I am doing an Ajax request with Javascript. I\'ve tried

Answer 1

I wanna thank jbl for pointing me to the right SO question. I got it now...

So, OK... the answer. If you ever wanted to set your own HTTP Header information, and then fetch it using cross-domain Ajax, or something like that, here are some extra HTTP Header you should set on your server side, before sending the response text.

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Methods: POST, GET");      
header('Custom-Header: Own-Data');
header('Access-Control-Expose-Headers: Custom-Header');

Example above uses PHP. But use your own language, what ever you use to set them.

When I asked this question, I had all of that except Access-Control-Expose-Headers. After putting that in, my Javascript Ajax can read the content of HTTP Header Custom-Header.
