How to use a remote server as a proxy?

Question

Nginx

I'm not good at fine-tuning nginx, but then in the server's message panel I noticed the "Proxy support" mark.
prntscr.com/e3xl43
prntscr.com/e3xm24
Do I understand correctly that I can use this server as a proxy, for example, for anonymous access to another site?
If so, can anyone use it for such purposes or not?
UPD apparently nginx is not able to work in the "direct" (transparent) proxy mode, here you need to use something else.

Answer 1

This is not in the sense of proxy. Here the proxy implies that nginx (web server) will give static files (which are listed), and dynamics (php) will be given to the apache web server

Answer 2

nginx is reverse proxy
you need squid
