The analogy of session ID to ticket number makes the whole concept more understandable 👍.

I've seen your full video series on Java Spring Boot, you explain everything so well that even complex topics look simple, I really love your style and way of teaching, you make everything sound interesting, you explain the right amount of theory and practical. Please keep it up. I'm surprised why you have only 343K subscribers, you should have much much more.

Kaushik, you are just mind boggling with explaining things. I must say there are loads of intelligent people in the world but not those many can explain and teach things as simply and as elaborately as they understand them. Kudos to you for being so informative and classy while explaining each and every thing. Have been following your channel since 2013 and still one of the favorite to understand anything new in web world.
