XMLHTTPRequest ResponseText is blank?

Hi,

For some reason, with the following snippet, I am always getting an
empty string in request.responseText (testing in FF 3.5) – any ideas?

I verified that the URI returns a value – here is a sample URI:

[url]http://www.gamechalk.com/simulator/simulator.php?req=Simulator%20coming%20soon!%20SMS%20Zork%20to%2041411%20to%20play.&user=100[/url]

var request = null;
function postCommand()
{
var uri = “http://www.gamechalk.com/simulator/simulator.php“;
var cmd = document.getElementById(“command”).value;
var user = “100”;
uri += “?req=” + escape(cmd) + “&user=” + user;
if (request != null && request.readyState != 0 &&
request.readyState != 4)
{
request.abort();
}
try
{
request = new ActiveXObject(“Msxml2.XMLHTTP”);
}
catch (e)
{
try
{
request = new ActiveXObject(“Microsoft.XMLHTTP”);
}
catch (E)
{
request = false;
}
}
if (!request && typeof XMLHttpRequest != ‘undefined’)
{
request = new XMLHttpRequest();
}
request.open(“GET”, uri, true);
request.onreadystatechange = function()
{
if (request.readyState == 4)
{
alert(request.responseText);
}
};
request.send(null);
}

Thanks in advance.
