Block all website except google traffic

I would like to block all websites except google peering via Mikrotik IP web proxy but there is no script available for it.our customer wants to only google traffic .
For example only http://www.google.com
youtube.com
gmail.com

it will open particular ip’s and remain all websites be denied same ip pool

If any body know about this script then please inform me with complete command line.

I shall be very thankful this kindness.

The problem i can see is when this pages call another one ( gadgets, plugins, etc) the page won’t look good.

Try and tell us what happened.
