Things were changed. However, headers should never be ignored, the old defaults

it turns out even sites like amazon.com don't understand HTTP, and made private
content (shopping carts) cacheable with that setting. So we tightened it down
even further, and the default requires explicit Expires or Cache-Control:
max-age headers.
Cool. Need to update the documentation then I guess.
Indeed, we'll take patches. Actually, talk to Igor if you are interested
in helping out :).
Setting it to 0 lets it cache "anything" that's not explicitly disallowed to
cache.
I set the
CONFIG proxy.config.http.cache.required_headers INT 0
and still nothing gets cached.
Hmmm, yeah, this is really difficult to debug with actually have either access
to your configs (including URLs, how you remap etc.), or your system. All I can
suggest is to debug with the -T tracer options (e.g. -T http.*) and examine why
it's not caching it.
How do I use this -T tracer option? Is there a page I can read?
Note sure if it's documented (someone else should chime in), but the
easiest is to simply do (after you shutdown everything with
trafficserver stop):
$ sudo traffic_server -T http.*
and send a request through the server and watch the action. What that
says is to show all tracer data where the tag matches the regex "http.*".
