hm... i am not really sure, is this a problem of the squid or not.
when iam browsing a page for example "www.cnn.com" , and then i delete all temp files of the internet explorer, then i open the page again, its again slow as without proxy, and i think im downloading all images again, NOT from the proxy, from the internet i think. must it be faster, when i browsed the site ? isn't it in the cache of the squid? thanks for helping!
