You can map a fully qualified URI or a partial URI by using an asterisk in the ruleset.
For example, you could apply the java_index_page_ruleset to an index.html page as follows:
www.sun.com/java/index.html/java_index_page_ruleset
or you could apply all pages in the java directory to the java_directory_ruleset, as follows:
www.sun.com/java/* /java_directory_ruleset
