You can test this code by using a user name of
first section of the script generates the following XML when the user clicks the login button:
<login username="JeanSmith" password="VerySecret" />
The server receives the XML, generates an XML response and sends it back to the SWF file. If the
password is accepted, the server responds with the following:
<loginreply status="OK" session="46597865D0B7884E007DEA7D" />
This XML includes a
which will be used in all communications between the client and server for the rest of the session.
If the password is rejected, the server responds with the following message:
<loginreply status="FAILURE" />
The XML node must load into a blank XML object in the SWF file. The following
loginreply
statement creates the XML object
// Construct an XML object to hold the server's reply
var loginReplyXML:XML = new XML();
loginReplyXML.onLoad = function(success:Boolean) {
The second statement in this ActionScript defines an anonymous (inline) function, which is
