Szczepan Hołyszewski asked:
I am looking for a way to quickly debug whether a given nginx conf file actually gets included directly or indirectly from main nginx.conf. Does nginx keep track of what config files it processes?
Solution may require openresty/lua and must not require Nginx+.
An ideal solution would add
X-Config-Read header(s) to every response, and would only need to be set up in one place, without having to modify all
server blocks, let alone all
nginx -T will show your configuration as it is read and parsed, including each time a configuration file is
included. The pathname of the file will be shown. If a file is included multiple times, it will be shown again, every time it is included.
Note that old versions of nginx do not have this feature; it was introduced in 1.9.2.
