title: How do I share data between pages on Google App Engine
body: <p>I'm a newbie programmer, working on my first web app (using App Engine), so forgive my ignorance.</p>
  
  <p>I have been modifying the Hello World program given by Google to try to make it do what I want.</p>
  
  <p>In their demo (http://code.google.com/appengine/docs/python/gettingstarted/templates.html) they have 2 classes that create 2 pages - one is the index.html, and the other handles a form, by putting the form data into a DB, and then redirecting back to the main page, which loads info from the DB.</p>
  
  <p>I would like to have a form on the main page where users submit a string, upon which various operations are performed, and the output is displayed on the main page.</p>
  
  <p>The problem is that the data from the form submitted by users goes to the form handler page, and I can't figure out how to give the output back to the main page.</p>
