INSTRUCTOR NOTE:

Edge Caching is not well documented, but there is an informative post on using it with Google App Engine : SETTING CACHE CONTROL HEADERS IN PYTHON TO TAKE ADVANTAGE OF GOOGLE APPENGINE’S EDGECACHE.

A sample code:

self.response.headers['Cache-Control'] = 'public, max-age=%d' % CACHE_EXPIRE
self.response.headers['Pragma'] = 'Public'
