0x01 written in front

Because of the work, it is often necessary to communicate between servers, or between processes, to assign tasks, and so on. With the socket operation, too much trouble, need to establish a connection, processing messages. So

You are ready to create a socket-Emulation HTTP Server helper class that can be called directly from WebClient.

0x02 HTTP protocol

My understanding: The HTTP protocol, is actually relies on the TCP/IP protocol, also can send the message through the socket, just said. The content format that is sent satisfies the HTTP conditions and can be interpreted as an HTTP protocol.

Common HTTP Headers . HTTP versions can also be written in 1.1.

http/1.0  okcontent-type:text/htmlconnection:keep-alivecontent- encoding:utf-8

0x03 TCP/IP

My understanding: The TCP/IP protocol is actually a classification of a class of protocols, and many protocols are based on this protocol to deliver the message. For more detailed information, please search for yourself.

Because, each time to start from the socket to write, write more only to find that the original need to write a common class, the point is not time-consuming.
