Workshop

The Workshop area is meant to reinforce your reading with a series of questions and exercises. The answers can be found in Appendix A, “Quiz Answers.”

Q&A

Q1: Why can't all the preferences be set at once?
A1: This is the biggest problem, in my mind, with the site. Because of the extensibility of the system, the table structure does not lend itself to showing all the attributes on a single page. If we had built a system that used a single table entry to store all the user's preferences, you could build a page that sets all attributes at once.
Q2:How can controlling the location of the layers be useful?
A2: Although we presented more of a technology demonstration in today's lesson than anything else, dynamic locations can be used to offer the user a variety of different screen layouts for her information.
Q3:What happens if a user tries to access the site from a computer other than the one with a cookie?
A3: The site will force the user to log in again. This will set a new cookie with the userID on the client's browser.
Q4:What happens if the user has cookies turned off?
A4: If the user does not have cookies turned on, the site is inaccessible. The cookie is checked when the content page is shown. If it doesn't exist, the browser is redirected to the login screen.
