for those who haven't heard my project for the last few months went live recently over at www.pcworld.com/shopping/ and I've spent the last week or two cleaning up after the transition, hunting down statically linked and code generated links to the the old /product/pricefinder site and rewriting them to point to the new URLS.
last week I created a set of rewrite rules which are triggered when our handy struts request processor decides that the old-style URL you're requesting is now bogus and gracefully reminds you that we've permanently redirected to a new place. These rewrite rules work wonderfully but are called after the original error is outputed to the logs, so each say we are getting something like 30,000 unneccesary errors in the log.
I was hunting around on google to see how likely it is that they are the referer for all of these hits and ended up running this search :
