Hi all,
I need help on managing KeepAlive on my nginx webservice.
Seeing error logs seems that many keepalive HTTP request are discarded by
Nginx. On client side this behaviour seems to be a timeout.
This is my code:
if(strlen(session->response) > 0) {
b->pos = (u_char *)session->response;
b->last = (u_char *)session->response +
strlen(session->response);
r->headers_out.content_type_len = strlen("application/json") -
1;
r->headers_out.content_type.data = (u_char *)
"application/json";
r->headers_out.status = NGX_HTTP_OK;
} else {
b->pos = (u_char *)r->args.data;
b->last = (u_char *)r->args.data + r->args.len;
r->headers_out.status = NGX_HTTP_NO_CONTENT;
}
r->headers_out.content_length_n = strlen(session->response);
b->memory = 1;
b->last_buf = 1;
ftime(&end);
felapsed=(int) (1000.0 * (end.time - start.time) +
(end.millitm - start.millitm));
ngx_http_send_header(r);
ngx_http_output_filter(r, &out);
ngx_http_finalize_request(r, r->headers_out.status);
Sometimes i Send a 200 Ok and some other times 204.
On nginx error log I see:
2016/07/04 11:06:11 [debug] 11643#11643: *13 http finalize request: 204,
"/mopub_bidr?" a:1, c:2
2016/07/04 11:06:11 [debug] 11643#11643: *13 http terminate request count:2
2016/07/04 11:06:11 [debug] 11643#11643: *13 http terminate cleanup count:2
blk:0
2016/07/04 11:06:11 [debug] 11643#11643: *13 http finalize request: -4,
"/mopub_bidr?" a:1, c:2
2016/07/04 11:06:11 [debug] 11643#11643: *13 http request count:2 blk:0
2016/07/04 11:06:11 [debug] 11643#11643: *13 http posted request:
"/mopub_bidr?"
Someone can me explain what means "finalize request: -4" ? It's an error?
Sometime into error log I found this error:
recv() not ready
and this seems the cause of client timeouts. how can I resolve it on nginx
conf?
Thanks a lot for help
Stefano G.
