How to get these information from the client with Javascript?

Question

How do I get these information? I am making a javascript (no jquery) that gets the plugins and user agent, and i want to include these also. I prefer client-side, I know how to do it with PHP.

I have seen it at http://browserspy.dk/headers.php and http://browserspy.dk/accept.php and https://panopticlick.eff.org/index.php?action=log&js=yes

Take a look into >document.referrer< and >navigation.userAgent<. — Xatenev, Aug 19 '14 at 10:36

Use this to get all the http headers:

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

I have tried these but it does not show the requested values – EnexoOnoma Aug 19 '14 at 10:38
Does it not show all the values or just some, which ones? – MartinWebb Aug 19 '14 at 10:42
He needs the request headers, not the response headers (= the headers sent by the client to the server). – Sebastien C. Aug 19 '14 at 13:47

var readHeader = (function() {

  // Hidden cache for the headers...
  var _request = undefined;

  return function(name) {
    //
    // We have a request cached...
    ///
    if (_request) {
      return _request.getResponseHeader(name);
    }

    //
    // We need to get the request...
    //
    else {
      // Do the request and wait for it to complete.
      _request = new XMLHttpRequest();
      _request.open("HEAD", window.location, true);
      _request.send(null)
      while (_request.readyState != 4) {};

      return _request.getResponseHeader(name);
    }
  }
})();
