I just got through working at Yahoo and they have valid reasons to want
all these behaviors. The thing I didn't like about the cache channel
implementation is it involves squid polling an RSS feed every few
seconds to determine which bits of the cache to invalidate.
I'm looking at launching a small site for a client and the
stale-while-revalidate/stale-on-error functionality is fairly critical.
I want to go with varnish, though. Front end cache server in India,
pulling content from the USA... lots of potential for slow/dead
connections back to the origin, so it would be great if Varnish would
serve stale content in this eventuality.
