This is the best ever explaination I have seen on an internet for the CORS topic, what an explaination!! Each and every details are covered here to understand it deeply and properly in a very easy language. I really appreciate. Thank you and and please keep it up. 🙂❤🙌

I had so many confusion with Same-Origin-Policy and CORS, you made it clear for me once and forever. The most brilliant part of your lecture is that you provide real step-by-step case of attacking and exploiting vulnerability. Most explanations in Internet are just few general statements that produce more questions than answers. Thank you!
