Aggressive caching of generated contents while maintaining auth info

Question

I'm using a Symfony 2 to generate my pages from data in a MySQL database. For most content, users have to be authenticated but the content itself does not change often and does not need to be customized for the users. So what's a good caching strategy for avoiding database calls while still maintaining the auth check?

Answer 1

Simply put, use Memcache to cache the SQL result-set for extended period of time.
