Nginx - Dynamic cache key for Aelia products

# Add Aelia cookies to the cache key. This will create multiple copies of each
# cached page (one for each combination of currency, country and province/state)
proxy_cache_key "$scheme$request_method$host$request_uri $cookie_aelia_cs_selected_currency$cookie_aelia_customer_country$cookie_aelia_customer_state$cookie_aelia_billing_country";

# 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 enter an incorrect configuration in Nginx, your web server could crash.
# 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.
