17.5. CNN

CNN (http://www.cnn.com) is the heaviest of the 10 top web sites in both total page weight (502K) and number of HTTP requests (198!). The main reason for this is the use of images to display text. For example, the image http://i.a.cnn.net/cnn/element/img/1.5/main/tabs/topstories.gif is the text "Top Stories," as shown in Figure 17-9.
