Sessions are another way to add “state” to a user’s interaction with a website. Traditionally, sessions values are stored on the server (in a file or a database table) and a reference identifier is stored in a cookie in the user’s browser. By default, Rails stores session data inside encrypted, signed cookies in the user’s browser. This approach prevents inspection, tampering, and session hijacking.
It's the session file that contains…the data that we want to store.…That's the main reason to use sessions.…With a cookie, the data is being stored…remotely on the user's browser,…where it can be read and altered.…Sessions store it on the server side,…so it's contents can't be read or altered.…All the user gets is the session identifier.…Using a session is just as easy as working with cookies.…You simply treat it like a hash.…So, we have session, and then inside square brackets,…we provide the key that we want to use to assign a value.…
