Hi RNfromTH,
In principle yes, but sometimes the ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is then denied for a Google.com service, and some websites do not allow you to visit from behind/via a proxy. I experienced when I really got to privacy stealth mode with a Mozilla browser on Tor with NoScript and RequestPolicy active Google denied me access because apparently they could not determine I was a human user or an automated process, so I had to fill in several captcha's before I could go on and through that I was identified. Even if you have set geo-location as false (via auto:config) you give out smears and smears of identifiable tracking data which combined will give out much more identifiable info there as geo-location, like here how I was identified by visiting the Norton Safe Web site (with all javascript disabled, all requests denied, and several special ABP block lists active) they have logged me as "user_pref_lang=ENG

and then I went the finjan URL checker I am to be identified like this ASPSESSIONIDAQSCQRRS=LMHGEJHCKCBGMJGOMMIFKGPH
Combine all these and you can be read like a book, chapter to verse. Forget it, there is nowhere to hide, and if you on a so-called anonymous proxy, the proxy website have all this info, and also sells it to earn on your clicks and profile, bet the majority of them does,
