About Handy-Httpd

Handy-Httpd is a simple, easy-to-use and easy-to-read implementation of the classic thread-based HTTP server. It uses a pool of worker threads to handle incoming requests, and follows the HTTP/1.1 connection style, where we accept a new client socket, read its request, send a response, and then close the socket.

It's written using plain D, with the help of the httparsed (opens new window) library by Tomáš Chaloupka for parsing HTTP requests. While we don't shy away from using D's garbage collector, a lot of effort has been made to minimize the amount of allocations done at runtime, so we can benefit from a class-based approach, without the performance hit that usually incurs.

As far as I (Andrew, the author of this library) am concerned, implementation of HTTP/2 or HTTP/3 is beyond the scope of my abilities, and would complicate this project unnecessarily. If you do need these features, and want to use Handy-Httpd too, don't fear! A common approach is to set up Nginx or some other high-performance server as a reverse proxy. It handles SSL, HTTP/2, load-balancing, and all the other fancy stuff that's already been figured out by people smarter than me.
