How to make a proxy for a website that has lost its domain using Cloudflare?

Question

Nginx

The situation is this: there is a site that is behind the Cloudflare proxy and has lost its domain. The site is available if the domain and IP are registered in HOSTS. Task: to make a proxy for this site, which will give access to it without the need to edit HOSTS. Preferably with minimal load on my server.

Answer 1

You must register the domain with a registrar. This is the only way without editing hosts.

Answer 2

Well, or register another domain + nginx + proxy_pass + set $host + ...
And there are no direct links to your (non-existent) domain on the site?
If there is, then you will have to do it differently, filter html, css, js and replace the old domain with a new one.
Something like https://www.ruby-forum.com/topic/178781
UPD. Didn't understand the task - nginx or squid? Should the site work for everyone or only those who have access to the proxy? If through a proxy, then it may be enough to add it to host, configure squid to a local name resolver, and that's it.

Answer 3

in 3proxy
allow * * www.site.name,site.name 80
parent 1000 tcp 1.2.3.4 80
deny *
proxy -a -n -p 80
or just
tcppm 80 1.2.3.4 80
(port forwarding)
