Canonicalization is the process of picking the best url when there are several choices, and it usually refers to home pages. For example, most people would consider these the same urls:
<!-- w --><a class="postlink" href="http://www.example.com">www.example.com</a><!-- w -->
example.com/
<!-- w --><a class="postlink" href="http://www.example.com/index.html">www.example.com/index.html</a><!-- w -->
example.com/home.asp
<!-- w --><a class="postlink" href="http://www.example.com">www.example.com</a><!-- w -->
example.com/
<!-- w --><a class="postlink" href="http://www.example.com/index.html">www.example.com/index.html</a><!-- w -->
example.com/home.asp
