is running in a web browser,
url must be in the same domain as the SWF file.

Example
For the following example, add a TextInput instance called
name_ti, a TextArea instance
called
result_ta, and a Button instance called submit_button to the Stage. When the user
clicks the Login button instance in the following example, two LoadVars objects are created:
send_lv and result_lv. The send_lv object copies the name from the name_ti instance
and sends the data to greeting.cfm. The result from this script loads into the
result_lv
object, and the server response displays in the TextArea instance (
result_ta). Add the
following ActionScript to Frame 1 of the Timeline:
var submitListener:Object = new Object();
submitListener.click = function(evt:Object) {
var result_lv:LoadVars = new LoadVars();
result_lv.onLoad = function(success:Boolean) {
if (success) {
result_ta.text = result_lv.welcomeMessage;
} else {
result_ta.text = "Error connecting to server.";
}
};
var send_lv:LoadVars = new LoadVars();
send_lv.name = name_ti.text;
send_lv.sendAndLoad("http://www.flash-mx.com/mm/greeting.cfm",
result_lv, "POST");
};
submit_button.addEventListener("click", submitListener);
