Our first example displays the web server’s time of day in a browser window (Fig. 23.4). When this app executes—that is, a web browser requests the app’s web page—the web server executes the app’s code, which gets the current time and displays it in a
Label. The web server then returns the result to the web browser that made the request, and the web browser renders the web page containing the time. We executed this app in both the Internet Explorer and Firefox web browsers to show you that the web page renders identically in different browsers—the page should look the same in most Web browsers.
