I'm developing a Flash application which use an web hendler to get/set data fomr/to a SQL server.
With the first call there'll a session be created to authorize the user for access.
Now I like to tell the Flash app when the session has a timeout.
For sure whould be one way to tell it to Flash next time the handler will be called by it.
A much better way would be to let something tell it to Flash when it ends without that Flash has to do a call but I've no idea how to do something like this.
