Aelia + NGINX + Cache

# IMPORTANT
# This is an example configuration file, and the settings apply to the entire server.
# You should probably adapt these settings to apply to a specific location, instead,
# so that they only affect your specific ecommerce site.
#
# If you are not familiar with Nginx configuration, we recommend to contact your
# developer, or hosting provider, who should be able to adjust the settings for you.
