A single visitor doesn't just mean a few incidental page requests; it also means an open connection (with a waiting thread) for as long as the visitor stays.───的访问不只是意味着一些偶然的页面请求；它还意味着在访问期间有一个持续打开的连接(带有等待线程)。
If interaction was possible after the initial data was served, and the connection was kept open, then the thread could not be released and the server would not be able to serve many users.───如果提供初始数据之后仍可能存在交互，那么将连接保持为打开状态，因此线程就不能释放出来，服务器也就不能为很多用户服务。
