Run TCPServer as a simple Web server

A TCPServer accepts incoming TCP connections. Here is a Web server that listens on a given port and returns the time.



require 'socket'

port = (ARGV[0] || 80).to_i

server = TCPServer.new('localhost', port)

while (session = server.accept)

  puts "Request: #{session.gets}"

  session.print "HTTP/1.1 200/OK\r\nContent-type: text/html\r\n\r\n"

  session.print "#{Time.now}\r\n"

  session.close

end
