Going nuts with this one. I have MYSQL database feed site with pages that return products with links like this at the bottom:
The server log is showing Googlebot getting links like /category/30/30/widget.html or /category/1621/1650/widgets.html. Google is getting lots of invalid URLs and getting 200's in the log for each one.
The problem is that I can't replicate this in the browser or even using Lynx on my Suse machine. It's a fairly new site and Yahoo and MSN aren't spidering it so I can't compare there.
