How exactly the Sessions and Cookies work? || Session Management || Spring MVC || @SessionAttributes

From this video onwards, I am going to cover session management from scratch. Let’s get it done step by step.
STEP 1: I will give you the basics idea about cookies and sessions.
STEP 2: I am going to implement cookies and session in our spring MVC / spring boot app
STEP 3: I will explain to you the use of spring’s annotations like @CookieValue, @SessionAttributes, @SessionAttribute
STEP 4: I will introduce the conversational scope and we will have another video on @SessionAttribute and its uses (Episode 14)
STEP 5: I will walk you through some advanced-level configuration for spring’s session management
