Hello World HTTP server using ZeroMQ * Build and install libzmq and CZMQ * Full article on http://hintjens.com/blog:42
// Minimal HTTP server in 0MQ
#include "czmq.h"
int main (void)
{
zctx_t *ctx = zctx_new ();
void *router = zsocket_new (ctx, ZMQ_ROUTER);
zsocket_set_router_raw (router, 1);
int rc = zsocket_bind (router, "tcp://*:8080");
assert (rc != -1);
while (true) {
// Get HTTP request
zframe_t *handle = zframe_recv (router);
if (!handle)
break; // Ctrl-C interrupt
char *request = zstr_recv (router);
puts (request); // Professional Logging(TM)
free (request); // We throw this away
// Send Hello World response
zframe_send (&handle, router, ZFRAME_MORE + ZFRAME_REUSE);
zstr_send (router, "HTTP/1.0 200 OK\r\nContent-Type: text/plain\r\n\r\nHello, World!");
// Close connection to browser
zframe_send (&handle, router, ZFRAME_MORE);
zmq_send (router, NULL, 0, 0);
}
zctx_destroy (&ctx);
return 0;
}

I'm not getting the connection to my browser closed when using this with zeromq 3.2.2 and relatively current czmq from github - am I doing something wrong?

Is there a Java version for this?

By the way, your code may have forgotten to close the router socket at the end.
