# Cmnd_Alias HTCACHECLEAN = /usr/local/sbin/htcacheclean
# pleroma ALL=HTCACHECLEAN, NOPASSWD: HTCACHECLEAN

# Please also ensure you have enabled:

# config :pleroma, Pleroma.Web.MediaProxy.Invalidation.Script, url_format: :htcacheclean

# 2. Replace 'example.tld' with your instance's domain wherever it appears.
# 3. This assumes a Debian style Apache config. Copy this file to
# /etc/apache2/sites-available/ and then add a symlink to it in
# /etc/apache2/sites-enabled/ by running 'a2ensite pleroma-apache.conf', then restart Apache.
