Check your access.log for the cache result code (TCP_REFRESH_MISS,
TCP_HIT, etc.) on the second request. See the Squid FAQ for
descriptions of result codes and the refresh algorithm:

    http://squid.nlanr.net/Squid/FAQ/FAQ-12.html#ss12.20

It's possible the object is volatile enough that Squid fetches a new
copy each time. If you like, post the relevant lines from your
access.log and store.log and we'll take a look at them.

I've seen slow browsers take a long time to load objects, even from a
local file. But let's check out Squid before placing blame :-)
