title: Parameters through postback
body: <p>I'm working with Ruby on rails 2.3.4 and I'd like to pass some parameters from one page to another ones the first one is submitted.</p>
  
  <p>For example:</p>
  
  <p>On the first page, I have a form that when it's filled a Preview button can be clicked to check all the info entered before submitting the form. That button redirects to another page with the info entered before, but I don't know how to get it in the second page. </p>
