Which flash technology is used for connections?
Client-side flash takes precedence over
server-side flash if both are configured
If conditions for client-side flash are not met,
fall back to server-side flash
Server-side flash requires Flash Player
enabled and configured on server
If conditions for server-side flash are not met,
no flash optimization is performed within ICA session
