+As usual, the first line is the site address.

 You will not usually need to configure this yourself; the [`file_server` directive](/docs/caddyfile/directives/file_server) will automatically add or remove trailing slashes from requests by way of HTTP redirects, depending on whether the requested resource is a directory or file, respectively.
 
-HTTP redirects are external, but you can internally [`rewrite`](/docs/caddyfile/directives/rewrite) add the slash if you want both URIs to be used for the same resource.
+However, if you need to, you can still enforce trailing slashes with your config. There are two ways to do it: internally or externally.
