(Starting today, we will open a new "security chapter" on security related HTTPS, SSL and TLS.Chapter 14 talks about some disadvantages of HTTP. One of them is "stateless", which is solved by adding cookies. The other two disadvantages - "plaintext" and "unsafe" are just HTTP itself. Cannot be solved. A new HTTPS protocol needs to be introduced.Why HTTPS?The simple answer is "because HTTP is not secure".)
