Squid sends a protocol request (hey, have you updated this page?) when it's
asked for a page. This is a single request, with a single response, but it
DOES generate traffic.

Also, some sites specifically tell proxies NOT to cache them (there is an
http header for that), and proxies can't cache dynamically generated pages
at all (.asps, anything that's a cgi script, form responses...)

My local SQUID expert says: If you're using Netscape, every time you select a 
bookmark it forces a complete reload of the page.


If all of these are null, come back with the problem and I'll look up the 
answer to the question you /did/ ask. :)
