WEBrick is an HTTP server toolkit that can be configured as an HTTPS server, a proxy server, and a virtual-host server. WEBrick features complete logging of both server operations and HTTP access. WEBrick supports both basic and digest authentication in addition to algorithms not in RFC 2617.
A WEBrick server can be composed of multiple WEBrick servers or servlets to provide differing behavior on a per-host or per-path basis. WEBrick includes servlets for handling CGI scripts, ERB pages, Ruby blocks and directory listings.
WEBrick also includes tools for daemonizing a process and starting a process at a higher privilege level and dropping permissions.
To create a new WEBrick::HTTPServer that will listen to connections on port 8000 and serve documents from the current user’s public_html folder:
require 'webrick' root = File.expand_path '~/public_html' server = WEBrick::HTTPServer.new :Port => 8000, :DocumentRoot => root
To run the server you will need to provide a suitable shutdown hook as starting the server blocks the current thread:
trap 'INT' do server.shutdown end server.start
The easiest way to have a server perform custom operations is through
EBrick::HTTPServer#mount_proc. The block given will be called with a
WEBrick::HTTPRequest with request info and a WEBrick::HTTPResponse which
must be filled in appropriately:
server.mount_proc '/' do |req, res| res.body = 'Hello, world!' end
server.mount_proc must precede
