HTTP 协议 的简单解释

At a glance, HTTP is a fairly simple, text-based protocol built on top of TCP/IP. Every HTTP session is initiated by establishing a TCP connection to the server, typically to port 80, and then issuing a request that outlines the requested URL. In response, the server returns the requested file and, in the most rudimentary use case, tears down the TCP connection immediately thereafter.
