Subject: Using net/HTTP - How to login and then retrieve data?

I'm new to Ruby, coming from Java. I need to write an HTTP client in
Ruby. I'm working in a Windows environment with Ruby 1.8 and RubyMine.

I've been working with net/http, and have written the code below, to
login to an HTTP server, then issue a POST to pull over some data, and
then logout. I can successfully Login, but the subsequent POST returns
an error indicating that I have Invalid Username/Password. I am also new
to HTTP processing, so I am not sure of the sequence of events that need
to take place for a successful Login-POST-Logout.

Please review my code and let me know what I need to do for the POST to
work.

Thanks!

require 'net/http'

#LOGIN
url1 =
URI.parse('http://imls.rets.fnismls.com/rets/fnisrets.aspx/imls/login')
req = Net::HTTP::Get.new(url1.path)
req.basic_auth 'myuser', 'mypass'
req.set_form_data({"RETS-Version" => "RETS/1.7", 'Accept' => '*/*',
'User-Agent' => 'Mozilla/4.0'})
res1 = Net::HTTP.start(url1.host, url1.port) {|http| http.request(req)}
puts res1.body  # This returns a 200 response and a listing of methods
that can be called, therefore this Login snippet works

#POST
url2Str = 'http://imls.rets.fnismls.com/rets/fnisrets.aspx/imls/search'
url2 = URI.parse(url2Str)
path = 'http://imls.rets.fnismls.com/rets/fnisrets.aspx/imls/search'
http = Net::HTTP.new(url2.host, 80)
data =
'SearchType=Property&Limit=15000&Format=COMPACT&Query=%28L_UpdateDate%3D2011-01-03T23:49:57%2B%29,%28L_UpdateDate%3D2011-01-04T23:49:57%2D%29&Class=BC_4'
headers = {
  'Accept' => '*/*',
  'User-Agent' => 'Mozilla/4.0',
  'RETS-Version' => 'RETS/1.7'
}
res2 = http.post(url2Str, data, headers)
puts res2.body  # This returns error <Net::HTTPUnauthorized 401 Invalid
Username/Password combination readbody=true>

#LOGOUT
url3 =
URI.parse('http://imls.rets.fnismls.com/rets/fnisrets.aspx/imls/logout')
req = Net::HTTP::Get.new(url3.path)
req.basic_auth 'myuser', 'mypass'
req.set_form_data({"RETS-Version" => "RETS/1.7", 'Accept' => '*/*',
'User-Agent' => 'Mozilla/4.0'})
res3 = Net::HTTP.start(url3.host, url3.port) {|http| http.request(req)}
puts res3.body  # This returns a 200 response
