How to write a simple webserver in Erlang?

Question

Using the default Erlang installation what is the minimum code needed to produce a \"Hello world\" producing web server?

Answer 1

Just one fix for Felix's answer and it addresses the issues Martin is seeing. Before closing a socket, all data being sent from the client should be received (using for example do_recv from gen_tcp description).

Otherwise there's a race condition for the browser/proxy sending the HTTP request being quick enough to send the http request before the socket is closed.
