How to Read an RFC
For better or worse, Requests for Comments (RFCs) are how we specify many protocols on the Internet. These documents are alternatively treated as holy texts by developers who parse them for hidden meanings, then shunned as irrelevant because they can’t be understood. This often leads to frustration and – more significantly – interoperability and security issues. However, with some insight into how they’re constructed and published, it’s a bit easier to understand what you’re looking at.
