It's probably doing HTTP HEAD requests on each element in that site
to verify that the cached copy hasn't expired.

I don't know off-hand if there's a parameter in squid that's the
equivalant of Netscape's `check once per session' thingie. Really,
though the website itself should be tagging the appropriate elements
of the document with expire times that keep the browser from checking
each element every time someone visits. (The RTTs for that sort of
thing alone will kill you, and for some reason a keep-alive connection
doesn't seem to help this all that much.)
