Part 4 – HTTP Basics

In the previous video was examined packets. We continue the discussion of web communications by taking a look into the core protocols of web app communications: HTTP and HTTPS.

HTTP consists of various types of requests with the fundamental ones by Get, Head, Delete, Post, and Put. The TCP port for HTTP is port 80.

The secure version of web app communications is HTTPS and it communicates over TCP port 443. It use SSL/TLS certificates granted by a certificate authority to vouch for the site owner’s identity. It also encrypts the data going across the connection for additional security.
