How do you make HTTP requests?
To make an HTTP call in Ajax, you need to initialize a new XMLHttpRequest() method, specify the URL endpoint and HTTP method (in this case GET). Finally, we use the open() method to tie the HTTP method and URL endpoint together and call the send() method to fire off the request.

What does an HTTP header look like?
HTTP headers let the client and the server pass additional information with an HTTP request or response.
