  What are "targets"?
Targets are the web pages (or web sites) that webbots and spiders use as resources. Since web pages change frequently, we decided to use canned web pages for all the web pages used (targetted) by the examples and projects in this book.

What are the bennefits of these targets?
These canned targets provide the following benefits to readers:

  1. There is no danger that these websites will change and adversely affect the operation of the example webbot projects in the book, ensuring that the book's example projects will work well into the future.
  2. These targets will allow you to focus on debugging your bots instead of worrying if the targetted websites have changed since the book was published.
  3. These targets provide a safe place for you to experiement.
