I am trying to add a fully custom HTTP header - in this case, as an example, Header = dog with value = cat. When I run this, instead of getting a new header, does it add the dog to the values in the request-access control headers? How to get a new custom header?
the code:
HR = new XMLHttpRequest(); HR.onload = function (e) { } HR.open("GET", URI); HR.setRequestHeader('dog', 'cat'); HR.send();
Request titles viewed with the Chrome Developer Tools:
