Hi,
go to the log view and check the webfilter logs for gucci.com and google.com.au and you will see the accesses to sites.
Also if I check the source code of gucci.com site you can see some javascript links to other sites like google, twitter etc.
<script type=" text/javascript" src=" http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js" ></script>
<script type=" text/javascript" src=" http://platform.twitter.com/anywhere.js?id=338501758-87yS7gRbhOnf8aupaCYL7kmvfZD2dVa5gI1bw7Gs&v=1" ></script>
I think (maybe I' m wrong) if you visit the site some scripts have to be loaded also, so you will probably see in the logs some google pages and twitter pages also. So it can give you some false data because the user didn' t ever visited these sites.
Please somebody correct me if I am wrong.
