I'm creating golang app with a proxy server as a pet project, and I want to have the possibility to set himself as a system proxy. Is it possible? And how?

Solution 1:[1]

Proxies are often configured through the HTTP_PROXY, HTTPS_PROXY and NO_PROXY environment variables. In Unix-style operating systems, these variables are inherited from the parent process to its child processes.

This being said:

  • your program can modify its own environment and start other processes as child processes (passing in the _PROXY variables).
  • your program may modify the shell startup scripts (like .bashrc, .cshrc), and a newly started shell will pick the values up and pass them to newly started processes.

But I am not aware that modifying the environment of other (active) processes is possible.
