    I'm rewriting a web server written in Rust for speed and ease of use▲68

    Hello! I got quite some feedback on a web server I'm building, so I'm rewriting the server to be faster and easier to use. I (and maybe some other contributors?) have optimized the web server performance, especially for static file serving and reverse proxying (the last use case I optimized for very recently). I also picked a different configuration format and specification, what I believe is easier to write. Automatic TLS is also enabled by default out of the box, you don't need to even enable it manually, like it was in the original server I was building. Yesterday, I released the first…

    A simple echo server for testing HTTP clients▲59

    I have developed an application called "echoserver" and I would like to share its details on Hacker News. The purpose of "echoserver" is to simplify the testing of HTTP clients. It functions as an echo server, meaning it responds to requests by echoing back the received data. This allows users to simulate various server responses and test their HTTP clients accordingly. With "echoserver," users can generate custom responses by specifying the desired status code, headers, and response body. This flexibility enables thorough testing of HTTP clients and simplifies the process of verifying…
