HTTP 请求从 Web 服务器分派到 CGI/FastCGI 进程 [英] HTTP request dispatch from Web Server to a CGI/FastCGI process

问题描述

为了进一步了解在 Web 应用程序中如何处理 HTTP 请求，像 Apache 这样的 Web 服务器如何将请求分派到其虚拟主机之一?不考虑框架(Rails/PHP/Java)而执行的初始程序是什么?如果有人可以列出以 Rails 为例的步骤(我知道 Rails)，我将不胜感激.提前致谢！

To gain more understanding of how HTTP requests are handled in case of web apps, how does a web server like Apache, dispatch a request to one of its Virtual Hosts? What are the initial programs executed irrespective of the framework (Rails/PHP/Java)? I would appreciate if someone can list the steps taking example of Rails (as I know Rails). Thanks in advance!
