OK. To clarify...

When mirroring a site, I want to retrieve incidental files from other sites,
like links to logos, CSS, Javascript, seals of approvals, etc., that appear in
the HTML pages I'm retrieving from the mirror site.  However, I do not want to
retrieve things of significance, like PDFs, Word docs, Powerpoints, video,
etc.

At the same time, I do not want ANYTHING, even incidentals, from sites like
googleanalytics.com or yahoo.com.

So I use the following rules...

-*
+*.jpg 
+*.gif 
+*.css 
+*.js 
+*.png
-*google-analytics*
-*paypal.com*
-*akamaitech.com*
-*google.com*

Am I on the right track here?
