What property can you examine to determine whether the browser is running on a mobile client 3. What property can you examine to determine whether the browser supports color or uses monochrome only
Suggested Practices
To successfully master the Program a Web Application, Write an ASP.NET Handler to Generate Images Dynamically for Display on a Web Page, and Add and Configure Web Server Controls exam objectives, complete the following tasks.
Program a Web Application
For this task, you should complete all six practices.
Practice 1
Download and install a non-Microsoft Web browser. Then, use the browser to open the last several Web applications you have created. Note how different ASP.NET controls behave when viewed with different browsers. In par ticular, notice how Web Parts behave differently. Web Parts are described in 9, Customizing and Personalizing a Web Application. If you have a production ASP.NET Web site available, add code that creates a log of browser types and capabilities for each new user. Examine the

variety of browsers and capabilities in your user base and think about how you might adjust your Web application to provide a better experience for all types of browsers.
Practice 3
Download one or two non-Microsoft browsers. Use those browsers to visit different Web sites and compare them side by side with Internet Explorer. Note how some Web sites display pages differently. Using the last production ASP.NET Web site you created, add appli cation-level error-handling to catch unhandled exceptions. Log exceptions to a file or database and let the application run for several days. Make note of whether any unhandled exceptions are occurring without your knowledge. Create a synchronous ASP.NET Web page that displays the output from a Web service located on a different server. Test the performance of the Web page when 10 requests are issued simultaneously. Then rewrite the Web page to be asynchronous. Retest the Web page and note whether performance changes. Deploy the ASP.NET Web page from the previous practice to both a Microsoft Windows 2000 Server computer running IIS 5.0 and a Microsoft Win dows Server 2003 computer running IIS 6.0. Test the performance of both the synchronous and asynchronous versions of the page on the different operating systems and note how the different platforms perform.
