Hi!

Current infrastructure:
We have nginx/1.7.1 as frontend for java application. We have special requirement, when java app goes down we need response with 204 error code instead 500 or 502 and this works like in charm for GET queries but nit for POST.

The question:
How I need ti change my config for POST queries.

The nginx.conf

upstream rtb {
keepalive 32;
server 127.0.0.1:8085 fail_timeout=0;
}


server {
server_name rtb.loopme.me;

open_file_cache max=1000 inactive=20s;
open_file_cache_valid 30s;
open_file_cache_min_uses 2;
open_file_cache_errors on;

log_not_found off;
access_log off;
error_log /var/log/nginx/error.log warn;

error_page 502 500 =204 @maintenance;
location @maintenance {
try_files $uri $uri/ /204/204.html =204;
}

location / {
try_files $uri @rtb;
}

location @rtb {
access_log /var/log/nginx/rtb.access.log;

proxy_set_header Host $host;
proxy_set_header HTTP_HOST $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header HTTP_X_FORWARDED_PROTO $scheme;
proxy_set_header X-Forwarded-Proto $scheme;

proxy_redirect off;
proxy_max_temp_file_size 0;

proxy_pass http://rtb;
}

Thanks in advance!
