The rel canonical thing is a way to actively update the Google index for a particular page and search term, and has been very effective in updating certain searches. For example, searching Google for "rewriterule" has long given the 1.3 Rewrite Guide, but within 24 hours of adding a rel canonical tag, it started pointing to the 2.2 mod_rewrite docs as the top hit. -- Rich Bowen rbo...@rcbowen.com :: @rbowen rbo...@apache.org
