I'm not sure what you mean::

	>>> cache.set("key", "val1")
	>>> cache.get("key")
	"val1"
	>>> cache.set("key", "val2")
	>>> cache.get("key")
	"val2"

Isn't that "replace"?

I think Mark is referring to the actual 'replace'
functionality of
memcached. From http://www.danga.com/
memcached/

replace -- sets in the cache only if the key already exists

As opposed to:

set -- unconditionally sets a given key with a given value

Ah, I see.

Django's cache only implements a minimal subset of functions
-- those 
supported by *all* cache backends.  You can always interact
with the memcached 
directly if you need "replace" (though frankly I
can't see why...)

For example we clear memcached like this:
  from django.core.cache import cache
  cache._cache.flush_all()
