I want to flush my cache whenever I post a new note on my application. So in my admin area, handled by a separate admin.py, I have this bit of code:

class NoteController(webapp.RequestHandler): def post(self, key): if key: note = db.get(key) else: note = Note()

note.content = self.request.get('content') note.put() logging.debug("New note created")

if memcache.flush_all() is True: logging.debug("Memcache flushed") else: logging.warning("Memcache flush failure")

self.redirect('/admin/')

However, it does not seem to do anything at all. The note gets created, but no log comes up in the dev log console and the cache remains intact. But when I run memcache.flush_all() in the Interactive Development Console manually, everything gets cleared in an instant.
