Use a trailing slash at the end of directory or root URLs
This avoids the server roundtrip: “the trailing slash tells the server to use the default document list for that folder and load that page. Without it the server first looks for a matching document name, then a folder with that name and use default doc list, finally performing a redirect (302) to that document. So using the trailing slash saves a certain amount of server load and aids the speed the document will load.”
