[squid-users] Anonymize surfing

Hello,

I want to anonymize surfing for that I have squid version 3.0 running in
transparent mode. I have

request_header_access From deny all
request_header_access Referer deny all
request_header_access Server deny all
request_header_access User-Agent deny all
request_header_access Via deny all
request_header_access WWW-Authenticate deny all
request_header_access X-Forwarded-For deny all
header_replace Referer unknown
header_replace User-Agent Mozilla/5.0 (Windows; U; MSIE 7.0; Windows NT 6.0; en-US)
header_replace Via 127.0.0.1
header_replace X-Forwarded-For 127.0.0.1

But it is still spewing the info on the net.

What could be wrong with this config?

Please suggest.

Thanks
