Getting Date from http header response

Question

Okay so I can access the HTTP ajax response header using

xhr.getAllResponseHeaders();

but it doesn\'t seem to get the Date with it, though

Answer 1

This Helped :

var req = new XMLHttpRequest();
req.open('GET', document.location, false);
req.send(null);
var headers = req.getAllResponseHeaders().toLowerCase();
alert(headers);
