Yahoo Zoeken

Your crawler is asking for strange URLs that never existed on my site, like /piopio/darkness-halo-bottom-camera.htm.  Are you looking on the wrong host?

Some web servers send a site navigation page or other response page with a "HTTP 200 OK" response instead of a "HTTP 404 Not Found" result for page-not-found conditions. To check on web server handling of page-not-found conditions, Slurp will occasionally send deliberately odd URLs built from random words to sites from which no 404 results have been seen. These URLs are built intentionally to not match any actual content at the site. We save information on the web server response to requests for non-existent pages so we can correctly recognize and remove obsolete URLs in our search database.

A Slurp check for 404 results from a web server consists of requests for up to 10 such URLs. The check for 404 behavior is not a normal part of Slurp site refresh, so such requests will be rare.
