Complete XMLHttpRequest Object Reference
Definition and Usage

headers of the XMLHttpRequest object.
A response header contains file information like length, server-type,
content-type, date-modified, etc.
Syntax

|
Example
The following code outputs all response headers in a HTML element with
id="headers":
<html>
<body>
<span id="headers"></span>
<script type="text/javascript">
xmlhttp=null;
if (window.XMLHttpRequest)
{// code for Firefox, Mozilla, IE7, etc.
xmlhttp=new XMLHttpRequest();
}
else if (window.ActiveXObject)
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
if (xmlhttp!=null)
{
xmlhttp.onreadystatechange = function()
{
if(xmlhttp.readyState == 4)
{
x=xmlhttp.getAllResponseHeaders();
document.getElementById("headers").innerHTML=x;
}
}
xmlhttp.open("GET", "note.xml", true);
xmlhttp.send(null);
}
else
{
alert("Your browser does not support XMLHTTP.");
}
</script>
</body>
</html>

Content-Length: 195 Content-Type: text/xml
