Subject: Proxy Server troubles

I've been working on a proxy server implementation for a project idea
I have.  But I've found that it only seems to work on certain pages,
and not on others.  I've distilled the problem down to a  simple
implementation, but it still occurs.  The code below will return a
(mostly) correct website if pointed at 'www.msn.com' but if pointed at
say 'slashdot.org' the browser refuses to display it, in both cases
the page is loaded correctly.  If anyone has any ideas I'd really
appreciate it.

===proxy.rb

require 'socket'
require 'net/http'
local_host = '192.168.0.6'
local_port = 8080

host = 'slashdot.org'
server = TCPServer.new(local_host,local_port)
while true
	Thread.start(server.accept) do |s|	
		data = ''
		while s.gets && !$_.nil?
			data += $_
			break if $_ == "\r\n" || $_ == "\n"
		end
		p "====Received: #{data}"
		net = Net::HTTP.new(host,80)
		response = net.get('/')
		s <<  "HTTP/#{response.http_version}
#{response.code}/#{response.message} \r\n"
		p "====Got back"
		response.each_header do |key,value|
				tmp = key + ": " + value + "\r\n"
				p tmp
				s << tmp
		end
		p response.body
		s << "\r\n" << response.body
		s.close # We're done with this request, bring on the next.
	end
end

====end
