What's the purpose for Google as a proxy? We often use office/school/university connections, usually those services are set to provide more safety, blocking the access to undesidered web sites (the "black list"). What you can do now is use Google translator service (language tools) as a proxy to bypass the restrictions set for our connection!
You just need to type the following URL:
(www.forbiddensite.com stands for the URL you need to go to...)
What you'll get is the translation (english to english!) of the page you want to see... your connection is directed to a google.com page so this page won't be blocked (would be blocked only with google.com on the black list), no matter what's the content.
Notice that the URL has been a little hacked because the parameter "langpair"(1) is set to "en|en" (english/english) so the page is processed by Google but you can keep the original language of the page (no need to translate!). If you need another language (e.g. french) you just need to set the parameter langpair to "fr|fr" and you'll be able to read french pages in french!
A couple of examples:
italian (my own homepage!)...
Last but not least: if you use this trick, you're not sure to protect your privacy, this kind of connection lets you see blacklisted pages but doesn't hide your IP address. Just go to
http://www.google.com/translate to see your IP is not hidden...
That's all, bye.
