I have the following rules in my swish-e.conf file..

   ExtractPath category regex !^/web/htdocs/([^/]+)/.*$!$1!
   ExtractPathDefault category unkown

When I index the files, the files found at /web/htdocs/*.html don't 
get 'unknown' as the value of their category, they get a null string 
  (""). Am I missing something?

thanks,
