The browser object model doesn't provide access to these headers but in IE 5 and newer you have an ActiveX Object Microsoft.XMLDOM which can request the page and return the headers as shown below:

<script language="JavaScript" type="text/javascript">
<!--
var http = new ActiveXObject('Microsoft.XMLHTTP');

// display headers of current document:
http.open('HEAD', location.href, false);
http.send();
alert(http.getAllResponseHeaders())

// or display headers of yahoo.com:
http.open('HEAD', 'http://www.yahoo.com/', false);
http.send();
alert(http.getAllResponseHeaders())

//-->
</script>

How to use it, depends on what you need it to do.
It fires off an AJAX request to the server to fetch just the headers for
the current page, so if you're on a page that has submitted some data or something
you'd get a duplicate request to the server.

If you just want to look at the headers for a given page really quickly int
the browser you can do it like this. (Adapted from above)
Copy the following string, and paste it into the location bar of your IE browser (doesn't
work in FF).
javascript:var http = new ActiveXObject('Microsoft.XMLHTTP');http.open('HEAD', location.href, false);http.send();alert(http.getAllResponseHeaders())

It'll fetch the headers for the page you're sitting on, and display them.
