title: How to access html request parameters for a .rhtml page served by webrick?
body: <p>I'm using webrick (the built-in ruby webserver) to serve .rhtml
  files (html with ruby code embedded --like jsp).</p>
  
  <p>It works fine, but I can't figure out how to access parameters
  (e.g. <a href="http://localhost/mypage.rhtml?foo=bar" rel="nofollow noreferrer">http://localhost/mypage.rhtml?foo=bar</a>)
  from within the ruby code in the .rhtml file.
  (Note that I'm not using the rails framework, only webrick + .rhtml files)</p>
  
  <p>Thanks</p>
