Sharen, .htaccess is specific to apache web servers, which you are running on. It's a hidden file, so will not show up on ftp clients (even though you can upload a file and rename it once there.) Another really good link for this is attached, they actually generate the script for you! If you have any problems, feel free to drop me a note.
