How to enable Logging with Headers for Nginx

Assuming you have a running setup and you want to enable logging with headers for debug and learning purposes ?

Add Lua

doas pkg_add nginx-lua--

and you get …

doas pkg_info -L nginx-lua--
Information for inst:nginx-lua-1.20.1p0

Files:
/var/www/modules/ndk_http_module.so
/var/www/modules/ngx_http_lua_module.so

Enable Modules in /etc/nginx/nginx.conf

add two lines on Top

load_module "modules/ndk_http_module.so";
load_module "modules/ngx_http_lua_module.so";

Enhance Logging

add the following to the “http” Section

log_format log_req_resp   '$remote_addr - $remote_user [$time_local] '
                          '"$request" $status $body_bytes_sent '
                          '"$http_referer" "$http_user_agent" '
                          '$request_time req_header:"$req_header" '
                          'resp_header:"$resp_header"';
