In my site there's declared an index.asp page. But in my stastistics I see also entries with index.html. How are these entries being created?
What response are the index.html have against them? 404 cannot be founds? Are these historic hits or are you constantly getting them?
I see these entries every day. They are registered in the log. And they do not appear as bad requests.
how old is your site?? If it is old enough then it might be that it was cached by some website like histroy machine and you are getting hits from there. I too have such entries but not much, even though i deleted all index.htm files long ago
