Understanding the Plain Http Request Was Sent To Https Port

A common misconception about HTTPS is that it protects all traffic. While it does, this article will explore why a "plain" HTTP request could still be sent to an HTTPS port.

1. HTTPS (Hypertext Transfer Protocol Secure) is often confused with plain HTTP due to similar URLs and protocols. However, the primary difference lies in the encryption method used between the client and server.
2. A "plain" HTTP request typically uses the "http://" protocol and may not include a specific port number unless explicitly requested by the client (e.g., ``).
3. However, some servers may choose to send plain requests over HTTPS, often due to performance or compatibility reasons. This is known as a "mixed" HTTP/HTTPS protocol.

The presence of links to various websites (e.g., Nginx, GitHub Pages) and a directory structure suggests an emphasis on building robust and secure online applications, which aligns with the goals of learning about vulnerabilities and best practices for testing them.
