Well, generally, the client writes the request
to the server, then waits for a response from
the server. So, in the client:
print $server "FOO request\n";
my $response = <$server>;
# or my $bytes_read = read($server, $response, 4192);
# or whatever--basically, just read from the server
And the server accepts connections, reads the
requests, handles them, then sends back data:
my $client = $server->accept;
my $request = <$client>;
# do something with the request
# generate a response
print $client $response;
close $client;
This is very dumbed-down, but it gets across
the general idea, I think. Is that what you
were asking?
