Detailed Description

If there is no Expires header already, fall back on Last-Modified
using the heuristic from
http://tools.ietf.org/html/rfc7234#section-4.2.2
to calculate a reasonable value.

Firefox also does something like this per
https://developer.mozilla.org/en-US/docs/Web/HTTP/Caching_FAQ
http://lxr.mozilla.org/mozilla-release/source/netwerk/protocol/http/nsHttpResponseHead.cpp#397
Unlike mozilla we limit this to 24-hr.

Member Function Documentation

◆ update_headers()

def update_headers (   self,
  response 
)
Update the response headers with any new headers.

NOTE: This SHOULD always include some Warning header to
      signify that the response was cached by the client, not
      by way of the provided headers.

Reimplemented from BaseHeuristic.

◆ warning()

def warning (   self,
  response 
)
Return a valid 1xx warning header value describing the cache
adjustments.

The response is provided too allow warnings like 113
http://tools.ietf.org/html/rfc7234#section-5.5.4 where we need
to explicitly say response is over 24 hours old.

Reimplemented from BaseHeuristic.
