Advantage Description :1. memcached is a memory cache that can read and write faster than regular files2. Can solve the problem of multiple server common sessionDrawback Description :1. Session data is stored in memory, persistence is deficient, but it is not a problem for session data2. You can also use other persistent systems to store sessions, for example: Redis,ttserver3. High-performance concurrency scenarios, the efficiency of cookies is much better than the session, so many large website
