When should you use this?

httpd is a HTTP1.1 server that is included with the standard Erlang distribution. If you don't need web sockets, server sent events, request body streaming, or higher HTTP versions then httpd could be a great choice!

If you need more than httpd offers then there are more sophisticated BEAM HTTP servers that you can add as a dependency and use, such as Ewe and Mist.
