As the disobedient person I am, I'm not going to do as you told me to.
:) I enabled log_mime_hdrs in squid.conf. Have a look at what I found:

This is from the Win98 browsing a single gif image. I've been at this
site before so the object is already in the cache. (I'm sorry about the
80+ character lines).

... And here we have the Linux-client browsing the same gif. Where did
that no-cache pragma come from!?

Now when I look closer, I see that there always seems to be a
DIRECT/blahblah statement when I browse from Linux? What's up with that?
(And what does it mean? :) )

As I said before, this isn't what you asked for, Henrik. If the above
output is of no use, I'm sorry. Next time I'll do as you say! I promise!
