retrieving all keys

[patrickk]

I´ve just done some research on this topic, but I couldn´t find an  
appropriate answer.

What I´d like to do is: List all memcache keys in the admin-section  
of a website (admins should also be able to delete certain keys, but  
that´s not the question here).
I´m currently using this code (http://effbot.org/zone/django- 
memcached-view.htm) to get some caching details, but I don´t know how  
I can list all the keys.

btw: I don´t know all the keys (of course).

Thanks,
Patrick
