I'm not a TCP guru at all. But i'm sure than to wait on an rebol open port it
is possible also if the port has not been open in TCP listen mode (which
requires server rights).
The sequence should be:
-client open a connection on server port 80 and send a message without
waiting
-client remembers the open port
-client makes some stuff and then wait on the already open port
-server receive message, makes some stuff and then reply on the same
connection
-client awakes and read the reply message
I think should work also a more complex mode:
-client opens a connection on server port 80 and sends a message with an
unique id
-client closes the port
-client remembers the unique id of message
-client makes some stuff
-server receives the message, closes the connection and makes some stuff
-client opens a new connection on server port 80 and sendes a message with
previous id
-client wait for a reply
-server receives the message, associates the id to the result and then
replies on the same connection
-server closes the connection
-client reads the reply message and closes the connection
