How to make a G-WAN servlet close its connection silently without sending any reply

Question

How to have gwan send no reply to some requests, i.e. make a servlet closed silently without building and sending a reply?

It is useful to reduce the out-going bandwidth from the server side.

For collecting data only, there's no need to respond anything to the client.

Answer 1

You can also close the connection from the servlet by doing something like (untested):

#include <sys/socket.h>

char buf[1024];
int s = (int)get_env(argv, CLIENT_SOCKET);
shutdown(s, SHUT_WR);
while(read(s, buf, sizeof(buf)) > 0);
close(s);
return 500;

Then return something like 500 like above so you don't have to build a reply.
