Q:

Add Trailing Slash to URLs

There are quite a few results for add trailing slash .htaccess on Google, but all examples I found require the use of your domain name, as in this example:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !example.php
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://domain.com/$1/ [L,R=301]

My problem is that a hard-coded domain name will not work on my local development machine. Is there a way to add trailing slashes without explicitly telling  mod_rewrite the domain name?

A:

You don’t need to specify the domain, you can simply use an absolute URL path:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*[^/])$ /$1/ [L,R=301]

That does also make a check for the URL scheme obsolete.

A:

This should work:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !example.php
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1/ [L,R=301]
