Massimo,

That fixed the "
ValueError: invalid literal for int() with base 10: 'NOT_FOUND' "
error for missing sessions.  Thanks!

The "
AttributeError: '_MemcacheClient' object has no attribute 'storage'"
error remains.  Maybe the code block and imports from gluon/cache.py
need to be added to gluon/contrib/memcache/__init__.py?

        if not app in self.meta_storage:
            self.storage = self.meta_storage[app] =
{CacheAbstract.cache_stats_name: {
                'hit_total': 0,
                'misses': 0,
            }}
