Does anyone know a good way to get the request header details using javascript? I had a quick go with ajax and its xmlhttprequest class, but I couldnt get it to work for me. Its worth noting I want to read the request headers, not the response headers.
Id much prefer a simple javascript DOM affair, but other than document.cookie I cant seem to find one for the other request headers. The AJAX code im using now is:
Code
<script>
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("HEAD", "<url>",true);
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState==4) {
alert(xmlhttp.getAllResponseHeaders());
}
}
xmlhttp.send(null)
</script>
Am I on the right track with AJAX, or am I gonna need something else?

Ok, i found this on a site, not sure but worth a try
Code
<script language="JavaScript"><!--
var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
var dateSent = null;
var dateComplete = null;
function RetrieveHTTPHeaders(url)
{
if (chkHEAD.checked)
xmlhttp.open("HEAD", "http:\/\/" + url, true); // Request just the header in an asynchronous call
else
xmlhttp.open("GET", "http:\/\/" + url, true); // Request all in an asynchronous call
And this is the site

Thanks for the reply, but im trying to actually understand this, not be a skid. Also,from my (very) limited knowledge of AJAX, that code doesnt do quite what I want, but it has some of the bits I was coding in it.
