title: How pass and read parameters between HTTP GET requests using Ruby on Rails?
body: <p>Now that <a href="https://stackoverflow.com/questions/4581075/how-make-a-http-get-request-using-ruby-on-rails">I am able to make a "simple" HTTP GET request</a> from a "<em>first website</em>" to a "<em>second website</em>", how is it possible to pass parameters safely in the URL using Ruby (on Rails)? </p>
  
  <p>URL example for the GET request: http ://www.example.com/index.html?param1=test1&amp;param2=test2</p>
  
  <p><strong>Then</strong>, in a "<em>second website</em>", <strong>I need to read parameters</strong> passed from the HTTP GET request of the "<em>first website</em>" to prepare the response. How can I make that?</p>
