In my previous article, I had written a very simple and basic reverse proxy. It is just like Nginx but without all the usefulness. In this new code, I have used Tokio provides runtimes for asynchronous programming. A runtime bundles services together and makes a single type of (for want of a better word) process, service, runtime, etc. This makes it easier to shut down, started, etc. In the code below, I have used TcpStream and TcpListener from the tokio library and not std. I have also spawned for tokio threads and within that, tokio tasks, which are sort of like green threads, but not quite because Rust does not natively support it.
