Question

I’m trying to send a lot of post-requests to the localhost:80 (nginx-server).

The headers I’m sending are:

POST /LINK HTTP/1.1
User-Agent: User agent
Host: localhost
Accept: */*
Connection: Keep-Alive
Content-Type: application/octet-stream
Content-Length: 16

DATA 16 BYTES

The pseudocode is:

TCPSocket sock('localhost', 80);
for(;;) {
   sock.sendPost();
}
sock.close();

But server returns first time:

HTTP/1.1 200 OK
Server: nginx
Date: Mon, 16 Apr 2012 14:54:26 GMT
Content-Type: application/json
Content-Length: 92
Connection: close

ANSWER 92 BYTES

So server doesn’t work with all another post-request from cycle.

Why does not Connection: Keep-Alive work and server returns Connection: close?

Answer 1

Set keepalive_timeout and keepalive_requests to proper values.
