Just wondering, could DGC be useful for keeping a port open on a firewall?
EG: Ping an endpoint occasionally to keep it alive while a lease exists?
The client doesn't know which port is open on a firewall, this
connection is set up by the firewall to allow replies from an external
host to be received by a client behind a firewall.
If a client provides a handback object to a service, the service can
continue to contact the client via that handback object, while the
connection remains alive and the firewall port open.
Thoughts?
Cheers,
Peter.
