Subject: Getting html page fields with webrick

Hi All,

I am playing with Webrick and I tried to change a little the example given 
with the packet but when I fill a html form and send it the fields values 
are empty (using GET method, Webrick doesn't accept POST method). How to 
fix it?
Thank you!

#!/usr/local/bin/ruby
require 'webrick'
include WEBrick

s = HTTPServer.new(:Port => 2000, :DocumentRoot => "/xitami/webpages")

class HelloServlet < HTTPServlet::AbstractServlet
  def do_GET(req, res)
    name = req['fname']
    email = req['email']
    st = "<HTML>Hello #{fname} -- #{email} </HTML>"
    res['Content-Type'] = "text/html"
    res.body = st
  end
end
s.mount("/hello", HelloServlet)


# HTTPServer#mount_proc(path){|req, res| ...}
#   You can mount also a block by `mount_proc'.
#   This block is called when GET or POST.

s.mount_proc("/hello/again"){|req, res|
  res.body = "<HTML>hello (again)</HTML>"
  res['Content-Type'] = "text/html"
}

trap("INT"){ s.shutdown }
s.start

it gives only "hello -- " as answer.

ps.
When I run the servlet, I get a warning:
"WARN TCPServer Error: Address family not supported by protocol - socket 
(2)"

Everything under Linux Slackware 9.0 and Ruby 1.8.0
