Look sample code for processing like this:

function process()
{
  if(xmlHttp)
  {
    try
    {
      xmlHttp.open("Get","test.txt", true);
      xmlHttp.onreadystatechange = handleRequestStateChange;
      xmlHttp.send(null);
    }
    catch(e)
    {
      alert("Can't connect to server\n" + e.toString());
    }
  }
}

From the code, we see 2 methods:

• open("method", "URL"[, asyncFlag[,"userName"[,"password"]]]) initialize the request parameters
• send(content) Performs the HTTP Request

We see 1 property:

• onreadystatechange Used to set the callback function that handles request state changes
