http's Introduction

http

A simple multi-threaded HTTP/1.0-ish file server. Single file, 300 LOC.

Handles only GET requests, serving files below the directory in which the server is started. Does Content-Type inference based on file extensions (e.g. html, js, png, jpg).

Currently disables any type of cacheing as I use it mostly for local development and want to avoid versioning mistakes.

Also has fledgling SSL support that has occasionally worked.

To run:

java net.http.Server

or if you can't run on priviledged ports (<1024), pick a high one:

java -Dport=8080 net.http.Server
java -Dport=8080 -Dssl=true net.http.Server

Good performance using Java's Native IO. Loadtest using acme.com's http_load:
