Some requests no tshowing up in access_log

Hi everybody,

I’m having following setup:

nginx <-unix_socket-> uwsgi -> django

What I noticed is, that some accesses which are successfully forwarded
to uwsgi are NOT logged in my nginx access_log file.

Is this the expected behaviour?
Ideally I would like, that every access is logged by nginx, sucnh, that
I can quickly check how many and which requests were hitting / going
through nginx.

in uwsgi.log I can see:
[pid: 1205|app: 0|req: 537/1453] xx.xx.xx.33 () {40 vars in 1794 bytes}
[Thu Jan 26 18:42:31 2012] POST /my_url/run?var=123 => generated 129
bytes in 94 msecs (HTTP/1.0 200) 3 headers in 174 bytes (1 switches on
core 0)

However I don’t see any corresponding request in nginx log.

This is driving me rather crazy while trying to debug some issues.

What could be the reason?

My nginx.conf
worker_processes 2;
events {
worker_connections 1024;
http {
include mime.types;
default_type application/octet-stream;

sendfile        on;
keepalive_timeout  65;

include sites-enabled/*;

uwsgi_temp_path  /etc/uwsgi/;




The probably relevant nginx config lines:
upstream django {
server unix:/var/sock/nginx.sock;

server {
listen 443;
server_name myserver;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;

ssl                  on;
# cert info . . . .
ssl_verify_client optional;
ssl_session_timeout  5m;
# cipher info
