Does it matter if URLs are written in capital or lowercase letters?
The main part of the URL, the hostname, can be written in either lowercase or capital letters. So, you could write either www.earthlink.net or WWW.EARTHLINK.NET. But individual directory or file names (essentially anything that comes after the .com or .net) ARE case-sensitive. You can’t, for instance, get to www.fast-net-usa.com/blink/ if you type www.fast-net-usa.com/Blink/ or www.gsta.net/bLink/. For this reason, you will most often encounter lowercase URL’s. If you do see file names written in some combination of uppercase and lowercase letters, be sure you’ve typed them into your browser exactly as they appear.
