(This lecture is the last lecture of flying sky. We have almost finished all the knowledge of HTTP.You have seen the new http / 2 and HTTP / 3 protocols before, and understand their characteristics and working principle. If you were exposed to HTTPS in security a few days ago, you may have questions again:"I just made great efforts to upgrade to HTTPS. This is another http / 2. Do you need to upgrade again?"Http / 2 is different from http / 2. Although it is a major upgrade of HTTP protocol, the resources supported by technology giants such as apple and Google are not as good as HTTPS.Until today, http / 2 is still in a "tepid" state on the Internet. Although many websites have been upgraded to http / 2, the popularity is far less than HTTPS.Then, you will naturally have such questions. How much benefit can you get from upgrading to http / 2? Is it worth it "?)
