18302	1.4 cache session storage is not backward compatible	slymsg@…	nobody	"I just updated from 1.3 to 1.4 using
django.contrib.sessions.backends.cache
and my sessions were lost.

Apparently the cache backend in 1.4 uses an
extra prefix to store the session_key in the cache:

KEY_PREFIX = ""django.contrib.sessions.cache""

Since this prefix cannot be configured from the
settings, I had to create a new cache session backend
based on the 1.4 version, setting KEY_PREFIX to """".

I cannot find anything about this change in the
changelogs. Did I miss something?"	Bug	closed	Documentation	1.4	Normal	invalid			Unreviewed	0	0	0	0	0	0
