SESSIONS AND FLASHWhat goes in a hash?

REVIEW: WHAT IS A SESSION?

A session is a hash that will store information on the client’s server until the session times out or is deleted.

Ex: creating a new session at login to remember a user until they log out or exit the application.

FUN FACTS

➤ Sessions are “lazily loaded”, meaning they will only load if you use them. If you choose not to use sessions, you don’t have to disable them.

➤ You can use the reset_session method to reset the entire session hash.

➤ To store data that persists from session to session, you can store a session in the CookieStore.
