HTTP Agreement - Introduction I used to think that the HTTP protocol is added, and now the HTTP is to send data in a clear text. HTTP (Hypertext Transfer Protocol, Hypertext Transfer Protocol), is used to transfer hypertext to local browsers from the WWW server. You can customize the content of the transfer through the protocol, thereby reducing network transmission. The HTTP protocol is a high-level protocol based on TCP / IP. The version HTTP / 1.1 is now widely used. The HTTP protocol is based on request / response mode. After the client is connected to the server, according to the protocol, send a request to the server, after the customer gets the request, returns the response information to the customer. The port number used by HTTP is usually 80. Regarding the specific content of the HTTP protocol, there are many online, no more, refer to the corresponding document. Next article I will use C to make a simple implementation of an HTTP protocol.
