I have seen this in SEO-poisoning type of webpage defacement.  They
anchor a javascript in the main website "frame" and it generates
optimization "links" using a numeric suffix or ?argument so that they
appear as separate links.  If the crawler is recognized  (e.g.,
googlebot) then the SEO page is returned.
