After your suggestion & watching the log & comparing each request to the
FAQ, I've now reconfigured a few things: I had my max file size set at
32M. I backed that off slightly. In my browser (MSIE 4.01)I changed
the cache setting to never check for a newer page and the amount to use
to the lowest amount (1% - no reason to cache the cache). This
increased the speed dramatically. I'm now convinced it's the browser.
However, if I change my setting to never page, then the .asp pages don't
refresh. If I set it to check every time I start, I see TCP_IMS_HITs in
my log and the speed is still slow. Can anyone tell me what the best
setting would be for IE40? (Other than to use something else...)

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:

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 :-)
