body: <p>Do I need to encode strings (eg URL) I pass as a POST form parameter?</p>
  
  <p>Ie I want to pass a URL I have to my web application (ruby on rails) as one of the form parameters.  So are there any potential characters in a URL/URI that would need to be encoded?  Or perhaps rails would handle this anyway?</p>
