send a cookie with XMLHTTPRequest (TVMLJS)

Question

I am developing an application for my AppleTV. The App will read movies from an online website that hasn't developed any API for this kind of thing.

I use XMLHTTPRequest to get the different URLs and have the user search for his movie, etc... Everything is working fine, except for a single request. To get the movie URL, I have to send a get request to a specific address (let's say http://example.com/getmovie.html) with a constant cookie (let's say mycookie=cookie).

I've tried using setRequestHeader:

var xhr = new XMLHttpRequest();
xhr.open("GET", url, false);
xhr.withCredentials = true;
xhr.setRequestHeader('Cookie', 'mycookie=cookie');
xhr.send();

But no cookie seems to be sent. I also tried setting the cookie with Document.cookie like I would have probably done in a "normal" js script (running in my browser) but no luck either.

This is extremely frustrating, especially since I'm stuck so close to the end of my app.

I guess cross-origin might be the issue but I'm able to get URLs without issues if I don't have to set cookies, so I am a bit lost there.

Please let me know how I can get http://example.com/getmovie.html with a specific cookie header.

Thanks for your help

Well... the problem here is the line xhr.setRequestHeader('Cookie', 'mycookie=cookie'); line just because the 'Cookie' header is reserved for the client browser to send the stored cookies. This means you are trying to do what the browser already does. When you send a any request, the client browser automatlycally will take all the cookies related to the site you are requesting and put them on the 'Cookie' header, you don't need to do anything else, if your cookie exist in your browser, it will be send.
