Everybody wants a web site

You have a killer idea for a web site. To destroy the competition, you need a flexible, scalable architecture. You need servlets and JSPs.

Before we start building, let’s take a look at the World Wide Web from about 40k feet. What we care most about in this chapter are how web clients and web servers talk to one another.
