With the disclaimer than i haven't used net/http much, the following
three forms all seem to post to manage.encoding.com and get back a 200
OK response.


require 'net/http'
require 'uri'

# this is the closest form to the one you tried
# note that the http protocol is excluded
# (presumably because we're explicitly constructing an HTTP object)

http = Net::HTTP.new('manage.encoding.com')
response = http.post('/', "xml=#{some_xml_data}")


# this form uses the post_form class method and a parsed uri
# note the trailing slash is necessary
# note also the (cleaner) use of a hash over a string for post params

url = URI.parse('http://manage.encoding.com/')
response = Net::HTTP.post_form(url, { 'xml' => some_xml_data })


# this form opens the tcp connection and http session,
# ensuring they are closed after the block executes

url = URI.parse('http://manage.encoding.com/')
Net::HTTP.start(url.host, url.port) do |http|
  response = http.post(url.path, "xml=#{some_xml_data}")
end
