# Pilot reverse proxy rules for routing selected Magento REST traffic to the
# Cloudflare continuity worker while keeping all other traffic on Magento.
#
# Usage:
# - include these location blocks inside the existing TLS vhost serving the
#   Magento domain that FarApp/Plytix currently calls
# - keep your current generic PHP/Magento locations after these more specific
#   routes
