The getResponseHeader() method of the XMLHttpRequest object is used to get the string value of a named HTTP response header (or the value null if the HTTP response headers have not been received yet or there was no specified header). CORS headers and cookie headers are filtered out and cannot be queried. If the HTTP response has 2 or more headers with the specified name, then this method will return a space separated string of all the header values concatenated together.
