Hi,--I am configuring the memcache backend to use with django and have the following things setup:CACHES = {

'LOCATION': '127.0.0.1:11211',
}
}
CACHE_MIDDLEWARE_ALIAS = 'django.core.cache.backends.memcached.MemcachedCache'
CACHE_MIDDLEWARE_SECONDS = 3 * 60 * 60 # 3 hours in seconds
CACHE_MIDDLEWARE_KEY_PREFIX = ''MIDDLEWARE_CLASSES = (

# the order of our middleware matters!

)I keep hitting the error message "Unable to parse connection string: "" which is coming from the memcache.py from the python-memcached binding. This is because the tuple of cache servers is empty instead of containing 127.0.0.1:11211.I have verified that the memcache daemon is up and running and have added and retrieved data from it.Hence, I believe that there is something wrong with my configuration and I have been trying to figure out what is wrong for hours. I hope someone can lend some assistance.Many thanks,navP.S. This is the first time I am setting up a cache so I may need some explanation of some concepts.
