Channel URLs are case sensitive, even if your Web server is not. That is, suppose you have a page called articles.html—sometimes you link to it as articles.html, other times as Articles.html. If you are on a Web server running in Windows 2000 or NT, these two URLs are treated as the same thing, and your Web site will look and act perfectly normal. But as far as your M-Business Sync Server is concerned, the articles.html page and the Articles.html page are two totally different pages, so it will request that page twice every time a user synchronizes.

If you are running your Web site on a UNIX-based server, page names are case sensitive. This means you probably will not run into this problem, because if you had a page called articles.html, linking to it as Articles.html would get you a 404-not-found error.
