Log in a user using Flash Remoting
If you are developing a Rich Internet Application with Flash and Flash Remoting, your ColdFusion application does
not need to be coded specially for a Flash login. The Flash Remoting gateway makes the user ID and password available
to the
tag in the

In your Flash code, you use the ActionScript
Flash SWF file displays the user ID and password fields, and uses their contents in the
follows:
if (inited == null)
{
inited = true;
NetServices.setDefaultGatewayUrl("http://localhost/flashservices/gateway");
gatewayConnection = NetServices.createGatewayConnection();
gatewayConnection.setCredentials(userID, password);
myService = gatewayConnection.getService("securityTest.thecfc", this);
}

Logging out users
After a user logs in, the ColdFusion user authorization and authentication information remains valid until any of the

• If your application does not use Session scope for login information, or if you use J2EE-based session identification,
the user closes all browser windows.
