Google Cache And Web Filtering

Hi fellow techies,
If you are using a webproxy, this tip is specially for you. What do you do when your proxy site is blocked by your network admin? Change to new proxy? come on, that too will be blocked soon.

Here is what worked for me:
lets say you are using, xyzproxy.com and its blocked.
try this link:
http://www.google.com/search?q=cache:xyzproxy.com

Your proxy's home page will open. From this page, when you start surfing, 9 out of 10 times you will be taken to someother unknown ip that xyz uses.

Thats all folks... Keep breaking rules... if you have any other alternative, feel free to share...
