  The commercial Harvest caching product does this from release 3.0 on.
  We do use this feature here, but not for reasons of security or privacy.
We use it because cookies are used by some web sites solely to prevent the
caching of pages at that site. It saves our end users time and money if the
proxy cache refuses to accept cookies from particular sites known to do
this. A more general policy of ignoring cookies on the transfer of graphic
objects is an interesting possibility I have not yet had the courage to
implement.
  It's worth bearing in mind that proxy caches tend to be paid for by
readers of material and not by publishers. It must be expected that their
administrators' actions will reflect that fact.
  Whether that implies that the use of cookies should be tightly restricted
by the standard to encourage proxy caches to accept them, or that what the
standard says may be disregarded anyway by many cache administrators, I'm
not sure.
