不知道在joomla上能不能用，没试过。发出来大家研究一下。
SEF advance is a Mambo 4.5 addon which will extend Mambo's built-in search engine friendly
URL functionality and raise it on a higher level.
Instead of ordinary Mambo SEF URLs like:
http://www.site.com/content/view/1/2/ which don't tell much about your content
you will get URLs in form:
http://www.site.com/Section_Name/Category_Name/Item_Name/
