OKHttp series of analysis we are going to start from six places, we will start with the basics of the network, because OKHttp involves Http protocol, so for the basic knowledge of Http, do a simple understanding, is very necessary. Three books are recommended: Illustrated Http

Overview THERE are four important HTTP phases, namely, 0.9/1/2/3, in which 1 is divided into 1.0 and 1.1. What protocol does HTTP/0.9 service for simple HTML file transfer only

In HTTP, the browser sends a request packet immediately after a connection is established. But now it's HTTPS...
