# === STATIC ASSET CACHING ===
# Proxy Cache Settings for static files ONLY.
# Nginx can cache static files and directly serve them without issuing calls
# to Apache on every static file request.
# By default Engintron will set a 1 minute (1m) cache time for static files.
# To increase, simply adjust the value for "proxy_cache_valid"
# Respects the different "Expires" header set per file type in "default.conf"
# for client-side caching.
# Every other header is ignored, stripped or reset from the request to
# maximize caching.
# This cache is turned off when certain criteria are met, e.g. when a site
# manager logs into WordPress' backend/admin section.
# Admin sections for CMSs
