"While working on a little project that made a site completely database driven, I realized that Yahoo and MSN incorrectly strip off trailing slashes in URLs (because I started seeing 404 page not found errors in my web logs).For example, the URL http://www.domain.com/directory/ is linked to as http://www.domain.com/directory from both MSN and Yahoo.This is bad for two reasons... first of all, it's just plain wrong, the two URLs could in theory be separate documents.  Second, it's a waste of bandwidth.  Most web servers are configured to add a slash to the end of a URL if there is no file that matches the name, and there *is* a directory with that name via a HTTP redirect.  So now, the end user's browser needs to make two requests to the server to get one document.The reason I figured it out is I *had* directories at one point, but moved to dynamic, database driven content.  So the web server wasn't redirecting them with the wrong URL because there was not a directory with that name any longer.Bad MSN, bad Yahoo... Naughty, boys."^^<http://www.w3.org/2001/XMLSchema#string>
