Detecting address of visited sited using ISA

[iamsmahd]

Hi.
I work in a company which uses Proxy server (ISA)for its internet connection and gets reports periodicaly in order
to find out who uses internet more and goes to which sites?

So when I want to go to a specific site, I do not enter its address in address bar of IE directly
but first go to

http://www.google.com

and like a normal search I enter its address and reach to the site.
I want to know that by still using this method, does superwiser of our LAN can detect the
sites which I have gone to them?

Thank you
