[https://www.varnish-cache.org/trac/wiki/VCLExampleDefault This diagram]
which provides a good overview of how Varnish works through the request-
response handling workflow doesn't include any mention of
"hash_always_miss".
Looking at the diagram, I had been working under the assumption that
Varnish didn't provide a way to update a cached document during a request
without either purging it before reaching "vcl_fetch", or letting the
cache object manually expire.
It would be good if that diagram could include:
* A change to the "obj in cache" block to show the influence that setting
hash_always_miss has.
* A clearer indication at what point the previously cached object is
evacuated from the cache - presumably that happens at the point we choose
to return "deliver" from "vcl_fetch", but it would be good if that was
made explicit.
