title: passing variables to a template on a redirect in python
body: <p>I am relatively new to Python so please excuse any naive questions.</p>
  
  <p>I have a home page with 2 inputs, one for a "product" and one for an "email." When a user clicks submit they should be sent to "/success" where it will say:
  You have requested "product"
  You will be notified at "email"</p>
  
  <p>I am trying to figure out the best way to pass the "product" and "email" values through the redirect into my "/success" template. I am using webapp2 framework and jinja within Google App Enginge.</p>
  
  <p>Thanks</p>
