The available options are:
* debug: If true, the traces are added as a HTTP header to ease debugging
* default_ttl The number of seconds that a cache entry should be considered
fresh when no explicit freshness information is provided in
a response. Explicit Cache-Control or Expires headers
override this value. (default: 0)
* private_headers Set of request headers that trigger "private" cache-control behavior
on responses that don't explicitly state whether the response is
public or private via a Cache-Control directive. (default: Authorization and Cookie)
* allow_reload Specifies whether the client can force a cache reload by including a
Cache-Control "no-cache" directive in the request. Set it to true
for compliance with RFC 2616. (default: false)
* allow_revalidate Specifies whether the client can force a cache revalidate by including
a Cache-Control "max-age=0" directive in the request. Set it to true
for compliance with RFC 2616. (default: false)
* stale_while_revalidate Specifies the default number of seconds (the granularity is the second as the
Response TTL precision is a second) during which the cache can immediately return
a stale response while it revalidates it in the background (default: 2).
This setting is overridden by the stale-while-revalidate HTTP Cache-Control
extension (see RFC 5861).
* stale_if_error Specifies the default number of seconds (the granularity is the second) during which
the cache can serve a stale response when an error is encountered (default: 60).
This setting is overridden by the stale-if-error HTTP Cache-Control extension
(see RFC 5861).
