In reverse proxy setups tuning this may make sense, but usually it is
better to address the second part of the equation and make the objects
refreshable. A patch adding a config directive for this constant is
accepted.
Objects are considered refreshable if there is a Last-Modified-Since
timestamp allowing Squid to use If-Modified-Since. Once ETag is supported
having a ETag also qualifies as being refreshable via If-None-Match but
this has not yet been done in Squid-3 (only exists as a proof of concept
patch for 2.5).
