HTTP may look simple at first glance, especially HTTP/1, but decades of protocol evolution and real-world demands have made it quite complex to implement correctly.

Why it matters: Misunderstanding HTTP’s complexity can lead to security flaws, interoperability issues, and wasted development effort.

The big picture: HTTP started simple but grew through many RFCs and extensions, making modern implementations intricate and heavyweight.

The stakes: Incorrect handling of headers, body endings, and protocol quirks can cause bugs, security vulnerabilities, and degraded web performance.

Commenters say: Many acknowledge HTTP/1.x is simpler than newer versions but still complex; it remains widely used due to efficiency and broad support despite challenges.
