5176	Bug in django.utils.cache._generate_cache_key(request, headerlist, key_prefix)	Eratothene	nobody	"Checked on latest SVN[[BR]]

If the !Order of middlewares goes like this:[[BR]]
'django.middleware.cache.!CacheMiddleware',[[BR]]
'django.contrib.sessions.middleware.!SessionMiddleware', [[BR]]
[[BR]]


And I want the order to be exactly like this, because !SessionMiddleware adds Vary on Cookie where appropriate.
Django dies on every request, which actually varyies on cookies. Generate_cache_key tries to get cookie into the cache key, what
is exactly what I want, but fails as it expects string not a !SimpleCookie. Path is trivial though..
