Odds are that your “origin” is not sending appropriate Cache-Control headers.
Even the default storage.config should have a small cache. HTTPD (Apache) would
by default not send any cache-control headers. If you don’t want to change
that, you can set
CONFIG proxy.config.http.cache.required_headers INT 1 # Or 0, but that’s
kinda crazy in general
Also, from your above config, this is almost always a bad idea (it becomes an
open proxy at this point):
CONFIG proxy.config.url_remap.remap_required INT 0
