I am currently using a memcached-based session store ( https://github.com/mperham/dalli ). From time to time the memcached server is unavailable ("No server available"), and then my users aren't able anymore to use the application. Currently I have doubts if a memcached-based session is the right decision.
Since I only store very few keys in a session I am thinking about switching back to a cookie store. Or should I consider using an ActiveRecord store? Any advice?
