4.2. Parsing HTTP Requests

The HTTPEchoProtocol class in Example 4-1 provides an interesting glimpse into HTTP in action, but it's a long way from being ready for use in a real web server. It doesn't even parse the request to figure out what resource the client is trying to access, or what HTTP method she's using. Before you try to build a real web application, you need a better way to parse and respond to requests. This lab shows you how.

4.2.1. How Do I Do That?

Write a subclass of twisted.web.http.Request with a process method that processes the current request. The Request object will already contain all the important information about an HTTP request when process is called, so all you have to do is decide how to respond. Example 4-2 demonstrates how to run an HTTP server based on a subclass of http.Request.
