Is there a Javascript only solution (no LiveConnect) to read from a url (i.e. http://www.blah.com/dyna.php) and put its contents in an object?

ha mo, Yar Dmitriev, Andy Sy, Colin Fraser,
Update:
XMLHTTP object (for IE 5+) is what you need. Though, the request is
limited within the host and the port of the script.
See http://msdn.microsoft.com/library/default.asp?url=/library/en-
us/xmlsdk30/htm/xmobjxmlhttprequest.asp
Example:
<html>
<div id="divDisplay">The response will be put in here</div>
<input type="button" onclick="sendData();" value="Send it!">
<script>
function sendData(){
var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
xmlhttp.Open("POST", "http://www.domain.tld/test.php",
false);
xmlhttp.Send("<timesheet>An impossibly useless
timesheet fragment</timesheet>");
divDisplay.innerHTML=xmlhttp.responseText;
}
</script>
</html>
People also point that similar feature named 'webrequest' exists for
Mozilla.
Thanks to guys from #javascript (EFNET).
====================
This is an interesting question, I have been trying to get a solution to
it since the first time I saw it, and have failed completely. So I am
giving up. I would say that it appears that the limitations of
JavaScript in its file handling capabilities mean this is just not going
to happen for you or anyone else. I am not going to say that this is the
final word here, but it is going to take a much better programmer than
me to find a solution I am afraid.
I am sorry I could not give a better answer, but someone else may.
====================
I found a way, but it relies on the contentDocument attribute which
afaik only works under Mozilla, =(. Maybe someone can try if it works
under IE6 already? MS is ignoring web standards yet again!
<html>
<script>
<!--
function geturl() {
tempFrame=document.getElementById("dummyIFRAME");
tempFrame.src=document.getElementById("url").value;
}
function showcontents() {
f2=document.getElementById("dummyIFRAME");
alert(f2.contentDocument.documentElement.innerHTML);
}
-->
</script>
<body>
<input id='url' type='text'></input><br>
<input onclick='javascript: geturl()' type='button'
value='get'></input><br>
<input onclick='javascript: showcontents()' type='button'
value='show'></input><br>
