What’s wrong with this piece of code (using XMPHTTPRequest)?

Hi,

Below is the code. I found the onreadystatechange event handler never got triggers. Any idea?

Thx
Tao
[INDENT] function OnGreetingsCleck()
{
//Sample.Aspnet.HelloWorld.Greetings(“TaoWang”, OnGreetingsComplete);

// get HTTP request object
var request = HTTP.newRequest();
// receive message
request.onreadystatechange = function(){
var b = 4;
if(request.readystate==4)
{
if(request.status == 200)
//OnGreetingsComplete(request.responseText);
alert(“I get message”);
}

}
// send
request.open(“GET”, “http://www.msn.com”); //”http://localhost/HelloWorldWebService/HelloWorld.asmx”);
request.setRequestHeader(“User-Agent”, “XMLHttpRequest”);
request.setRequestHeader(“Accept-Language”, “en”);
request.send(null);
}[/INDENT]
