I have rewritten my net/http script that I had questions on a couple of 
days ago using httpclient but am stuck on the NTLM authentication piece. 
This is what I have so far:

#!c:/ruby/bin/ruby.exe
CERT_FILE = "c:/certs/jim_nopw2.pem"
CA_CERT = "c:/ca_certs/servers_ca.cer"

require 'rubygems'
require 'httpclient'  # using v2.1.2 and rubyntlm 0.1.1 installed

client = HTTPClient.new
client.ssl_config.set_trust_ca(CA_CERT)
client.ssl_config.set_client_cert_file(CERT_FILE, CERT_FILE)

# This fetches the page but 401 error because not authenticated through NTLM
resp = client.get("https://some_website.com/default1.asp")

# Not sure how to turn on NTLM authentication and feed arguments. I 
tried this but still get 401 error
#resp = client.request('GET', "https://some_website.com/default1.asp", 
{'username' => 'DOMAIN\username', 'password' => 'password'})
puts resp.content
puts resp.status

Thanks again for any and all help.
