Force Favicon Requests to Correct Location - For whatever crazy reason, perhaps evil-doing site scanners, requests to a web server for a favicon in all known crevasses of the site are fairly common. Since that file probably only actually exists in the root directory of your site, these requests result in a 404. If you server up a fancy, user-friendly 404 page, this can add up to a ton of bandwidth for no good reason.
