When you type a URL like www.wrox.com in your web browser
and press Enter, the browser sends a request to the web server at
that address. This is done through HTTP, the HyperText Transfer
Protocol. HTTP is the protocol by which web browsers and web
servers communicate. When you request the URL, you send a
request to the server. When the server is active and the request is
valid, the server accepts the request, processes it, and then sends
the response back to the client browser. The relationship between
the request and response is shown in Figure 1-8.
