[squid-users] Some Websites not loading correctly

Hello,

my latest configuration of squid is running fine, but i have problems
with some websites e.g.:

http://route.tomtom.com Here the map ist not displayed.
http://www.logitech.com/de-de/keyboards/keyboard-mice-combos This
website stops loading.

If I try it without squid both websites are displayed correctly.

Some ideas?

TIA, Florian
