I have entries in my sitemap that look like:

http://www.domainname.com/directory/index.html

In my sitemap error section, I am seeing the follwing:

http://www.domainname.com/directory/ In Sitemap 404 (Not found)

Because I am using a CMS and thus a SEF URL component, there isn't really an index.html file or a directory called "directory". Granted, the url still lands you at the correct place.

Why is Google lopping off the index.html in its search? Do you know of any way to fix this?
