Some confusion exists concerning the proper use and interpretation of HTTP version numbers, and concerning interoperability of HTTP implementations of different protocol versions. This document is an attempt to clarify the situation. This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind.
