Proxying and modifying requests in nginx, How to do it right?

Question

Nginx

Suppose you need to modify the request when accessing the nginx proxy server.
That is, the nginx server, having received such a request 123.123.123.123:18085/?url=222.222.222.222%3A8085 , should redirect the request to the server 222.222.222.222:8085

Answer 1

Suppose nginx does not receive a request in the form that you described - it receives a GET /?url=222.222.222.222%3A8085. If you want to get an argument and use it as part of a new url, there are built-in variables for this + the rewrite module .
