(Before giving a formal lecture, let's take a look at what "weapons" HTTP has on hand.In terms of protocol, HTTPS strengthens the security of communication link and HTTP / 2 optimizes the transmission efficiency; In terms of application, nginx / openresty improves website service capability and WAF resists website intrusion attacks. Speaking of this, do you think there is something missing?Yes, in the application field, there is still a lack of a service to accelerate the HTTP protocol externally. That is what we are going to discuss today.CDN (content delivery network or content distribution network), Chinese name is "content distribution network".)
