##
# = WEB server toolkit.
#
# 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.
#
# == Security
#
# *Warning:* WEBrick is not recommended for production. It only implements
# basic security checks.
#
# == Starting an HTTP server
#
# 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
#
# == Custom Behavior
#
# The easiest way to have a server perform custom operations is through
# WEBrick::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
#
# Remember that +server.mount_proc+ must precede +server.start+.
#
# == Servlets
#
# Advanced custom behavior can be obtained through mounting a subclass of
# WEBrick::HTTPServlet::AbstractServlet. Servlets provide more modularity
# when writing an HTTP server than mount_proc allows. Here is a simple
# servlet:
#
# class Simple < WEBrick::HTTPServlet::AbstractServlet
# def do_GET request, response
# status, content_type, body = do_stuff_with request
#
# response.status = 200
# response['Content-Type'] = 'text/plain'
# response.body = 'Hello, World!'
# end
# end
#
# To initialize the servlet you mount it on the server:
#
# server.mount '/simple', Simple
#
# See WEBrick::HTTPServlet::AbstractServlet for more details.
#
# == Virtual Hosts
#
# A server can act as a virtual host for multiple host names. After creating
# the listening host, additional hosts that do not listen can be created and
# attached as virtual hosts:
#
# server = WEBrick::HTTPServer.new # ...
#
# vhost = WEBrick::HTTPServer.new :ServerName => 'vhost.example',
# :DoNotListen => true, # ...
# vhost.mount '/', ...
#
# server.virtual_host vhost
#
# If no +:DocumentRoot+ is provided and no servlets or procs are mounted on the
# main server it will return 404 for all URLs.
#
# == HTTPS
#
# To create an HTTPS server you only need to enable SSL and provide an SSL
# certificate name:
#
# require 'webrick'
# require 'webrick/https'
#
# cert_name = [
# %w[CN localhost],
# ]
#
# server = WEBrick::HTTPServer.new(:Port => 8000,
# :SSLEnable => true,
# :SSLCertName => cert_name)
#
# This will start the server with a self-generated self-signed certificate.
# The certificate will be changed every time the server is restarted.
#
# To create a server with a pre-determined key and certificate you can provide
# them:
#
# require 'webrick'
# require 'webrick/https'
# require 'openssl'
#
# cert = OpenSSL::X509::Certificate.new File.read '/path/to/cert.pem'
# pkey = OpenSSL::PKey::RSA.new File.read '/path/to/pkey.pem'
#
# server = WEBrick::HTTPServer.new(:Port => 8000,
# :SSLEnable => true,
# :SSLCertificate => cert,
# :SSLPrivateKey => pkey)
#
# == Proxy Server
#
# WEBrick can act as a proxy server:
#
# require 'webrick'
# require 'webrick/httpproxy'
#
# proxy = WEBrick::HTTPProxyServer.new :Port => 8000
#
# trap 'INT' do proxy.shutdown end
#
# See WEBrick::HTTPProxy for further details including modifying proxied
# responses.
#
# == Basic and Digest authentication
#
# WEBrick provides both Basic and Digest authentication for regular and proxy
# servers. See WEBrick::HTTPAuth, WEBrick::HTTPAuth::BasicAuth and
# WEBrick::HTTPAuth::DigestAuth.
#
# == WEBrick as a daemonized Web Server
#
# WEBrick can be run as a daemonized server for small loads.
#
# === Daemonizing
#
# To start a WEBrick server as a daemon simple run WEBrick::Daemon.start
# before starting the server.
#
# === Dropping Permissions
#
# WEBrick can be started as one user to gain permission to bind to port 80 or
# 443 for serving HTTP or HTTPS traffic then can drop these permissions for
# regular operation. To listen on all interfaces for HTTP traffic:
#
# sockets = WEBrick::Utils.create_listeners nil, 80
#
# Then drop privileges:
#
# WEBrick::Utils.su 'www'
#
# Then create a server that does not listen by default:
#
# server = WEBrick::HTTPServer.new :DoNotListen => true, # ...
#
# Then overwrite the listening sockets with the port 80 sockets:
#
# server.listeners.replace sockets
#
# === Logging
#
# WEBrick can separately log server operations and end-user access. For
# server operations:
#
# log_file = File.open '/var/log/webrick.log', 'a+'
# log = WEBrick::Log.new log_file
#
# For user access logging:
#
# access_log = [
# [log_file, WEBrick::AccessLog::COMBINED_LOG_FORMAT],
# ]
#
# server = WEBrick::HTTPServer.new :Logger => log, :AccessLog => access_log
#
# See WEBrick::AccessLog for further log formats.
#
# === Log Rotation
#
# To rotate logs in WEBrick on a HUP signal (like syslogd can send), open the
# log file in 'a+' mode (as above) and trap 'HUP' to reopen the log file:
#
# trap 'HUP' do log_file.reopen '/path/to/webrick.log', 'a+'

# HTTPAuth provides both basic and digest authentication.
#
# To enable authentication for requests in WEBrick you will need a user
# database and an authenticator. To start, here's an Htpasswd database for
# use with a DigestAuth authenticator:
#
# config = { :Realm => 'DigestAuth example realm' }
#
# htpasswd = WEBrick::HTTPAuth::Htpasswd.new 'my_password_file'
# htpasswd.auth_type = WEBrick::HTTPAuth::DigestAuth
# htpasswd.set_passwd config[:Realm], 'username', 'password'
# htpasswd.flush
#
# The +:Realm+ is used to provide different access to different groups
# across several resources on a server. Typically you'll need only one
# realm for a server.
#
# This database can be used to create an authenticator:
#
# config[:UserDB] = htpasswd
#
# digest_auth = WEBrick::HTTPAuth::DigestAuth.new config
#
# To authenticate a request call #authenticate with a request and response
# object in a servlet:
#
# def do_GET req, res
# @authenticator.authenticate req, res
# end
#
# For digest authentication the authenticator must not be created every
# request, it must be passed in as an option via WEBrick::HTTPServer#mount.
