Pass string from file to Nginx variable?

Question

Nginx

Hello! The crux of the matter is this. We have nginx without php and everything else. At a certain request, the server gives the file, let it be file1.txt. This file contains the name of the second file, let's say file2.txt. How can I pass the name of the second file to the nginx variable in order to use it later in the server config?

Answer 1

try nginx + lua

Answer 2

Nginx parses the file only when include. In other cases, it simply gives the file without analyzing its content.
If you need to dynamically change variables inside Nginx, then you can use $arg_name (from the request) or $sent_http_name (from the response HEADER).
