Apache sub folder configuration for Trailing Slash Solution - http://josephspurrier.com/trailing-slash-solution/

.htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /test/

    # Strip main index.php and query string
    RewriteCond %{THE_REQUEST} ^GET./+test/+index\.php\?
    RewriteRule . /test/? [R=301,NE,L]

    # Strip multiple slashes and query string
    RewriteCond %{THE_REQUEST} (.*)//(.*)
    RewriteRule (.*) /test/$1? [R=301,NE,L]

    # If real file has a trailing slash, remove it and strip the query string
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^(.*[^index.php])/$ $1? [R=301,NE,NC,L]

    # Check for file
    RewriteCond %{REQUEST_FILENAME} !-f

    # Send all other requests to index.php
    RewriteRule . index.php [L]
</IfModule>

If you place a dynamic application using the Front Controller pattern (index.php) in a sub folder, place this file in the same sub folder and then change the 5 instances of 'test' to your folder name. This also requires you to use the Apache root folder configuration here: https://gist.github.com/josephspurrier/9835946.

By using these two scripts, both applications will handle pages the same.
