Session Management

Mechanism used by web applications to store information about a user's interaction with the application over multiple requests:

• Sessions are typically stored on the server-side and consist of a session ID, which is sent to the client and used to retrieve the stored session data.

• The server typically tracks this session ID using a cookie (commonly PHPSESSID), which is sent with every subsequent request.

The session data itself can be stored in several locations:

• Files

• Database

• Redis

• Memcached

• Or other custom drivers.

Its security is critical to prevent issues like session hijacking and fixation.
