Session Tutorials in Django

Session Tutorials in Django:

A session is a special object in Django that can store the data of an application that can be created by one method and used in multiple methods.

A session is also called a server-side object that provides persistent data to use on multiple screens.

When we create a login option then the session provides individual user data, login time, logout time, page security, etc.


It is called Server Side Object because it will be created by Web Server and store data under client machine by Browser Cookie.
