title: RoR: POST to a page using raw form data. How?
body: <p>Is there a ruby method to POST form data encoded in "x-www-form-urlencoded" as specified here? <a href="http://www.w3.org/MarkUp/html-spec/html-spec_8.html" rel="nofollow">http://www.w3.org/MarkUp/html-spec/html-spec_8.html</a></p>
  
  <p>I am aware of Net::HTTP.post_form, but because I have several values to post which share the same name I can't use a hash, which is required by that method.</p>
  
  <p>To clarify, I have a string of the form "value1=x&amp;value1=y&amp;value1=z&amp;value2=a&amp;value3=b" and I want to be able to POST it to another page. How can I do this?</p>
