It's a personal project for a personal need but that I would like to find so I share.
It's a simple server in Rust that redirects according to a configuration file.
The file is expected under /usr/src/fucking_simple_redirect/domains.config. You can change the location with the environment variable FUCKING_CONFIG
The config file is simple. One redirect per line. The line must with the following pattern otherwise it will be ignored:
redirect [HOST] to [URL]
If the line ends with temp, the redirect will be temporary.
redirect 127.0.0.1:8080 to https://google.com temp
The server listens on 127.0.0.1:8080 by default, you can change with FUCKING_HOST and FUCKING_PORT.
