I first started seeing this a little over two months ago on a site I run but now I am seeing it on several others I manage. It appears the bot is trying to parse the URL into folders and this is what's causing the issue.
For instance this URL is correct:
But then Bing tries to access this URL:
And then this URL:
/Proposed-Alaska-Gun-Law-SCR6 (sorry cant post more than 2 complete links)
The second two of course throwing a 404.
This site has over 67,000 pages and this error on their part is driving us nuts, loading up the error logs with tens of thousands of 404 for URLs that are incorrect.
About a month ago I built an xml sitemap script hoping that would solve the issue. I submitted it to Google and Bing via the webmaster tools section. Google correctly indexed all 67,000+ pages while Bing is sitting there trying to parse these non existent URLs.
Has anyone else seen this and more importantly does anyone know how to either stop this or contact Bing to get them to stop?
