I see that some servers will stop the connection once a single request is done by sending [FIN, ACK]
From wiki,
A connection can be "half-open", in which case one side has terminated its end, but the other has not. The side that has terminated can no longer send any data into the connection, but the other side can. The terminating side should continue reading the data until the other side terminates as well.
In case I want to speed up the requests by avoiding repeating handshake per request. Is it possible for the client to keep communicating even the server terminated its end? Will there be any response from the server or the server just read my request without responding?
Update:
Just tested, if I delayed my [FIN, ACK] packet, there is no [ACK] packet from the server. Another question, if the server doesnt respond to it, will it process my request?
