HTTP/1.1 just got a major update – somehow I missed this last month.
The IETF just published several new RFCs that update HTTP/1.1:
- RFC 7230: Message Syntax and Routing
- RFC 7231: Semantics and Content
- RFC 7232: Conditional Requests
- RFC 7233: Range Request
- RFC 7234: Caching
- RFC 7235: Authentication
- RFC 7236: Authentication Scheme Registrations
- RFC 7237: Method Registrations
- RFC 7238: the 308 status code
- RFC 7239: Forwarded HTTP extension
These documents make the original specification for HTTP/1.1 obsolete. As a HTTP geek, this is a big deal.
RFC 2616, which was written more than 15 years ago, was the specification everybody has implemented, and I suspect many of you occassionally have used as a reference.
