Hi,

range replies aren't cacheable in squid25 and I doubt that it'll
be implemented in squid26.

To be perfectly honest, until the internals are reworked range
reply caching/aggregation isn't likely to happen. So unless
someone else has any ideas .. :-)

Part of the reworking (which I'm slowly doing) will involve the
range requests being totally uncacheable - ie, all objects
with a Range header will be passed through rather than the
entire object being read and a part returned. THAT should
be in squid-HEAD soon.
