Как исключить дубль сайта со / на конце

# MODX supports Friendly URLs via this .htaccess file. You must serve web
# pages via Apache with mod_rewrite to use this functionality, and you must
# change the file name from ht.access to .htaccess.
#
# Make sure RewriteBase points to the directory where you installed MODX.
# E.g., "/modx" if your installation is in a "modx" subdirectory.
#
# You may choose to make your URLs non-case-sensitive by adding a NC directive
# to your rule: RewriteRule ^(.*)$ index.php?q=$1 [L,QSA,NC]
