Today, I have crossed the long history of thirty years with you and reviewed the entire development process of the HTTP protocol. Here is a brief summary of today's content:
1. The HTTP protocol started a paper by Tim Berners-Lee thirty years ago;
2. HTTP / 0.9 is a simple text protocol and can only obtain text resources;
3. HTTP / 1.0 establishes most of the technologies currently in use, but it is not a formal standard;
4. HTTP / 1.1 is currently the most widely used protocol on the Internet, and its functions are also very complete;
5. HTTP / 2 is based on Google's SPDY protocol, focusing on performance improvement, but not yet popular;
GO's http library supports HTTP / 2 protocol by default. As long as we use TLS, the HTTP / 2 feature will be enabled by default.
6. HTTP / 3 is based on Google's QUIC protocol, which is the future development direction.
