If you want to do it on the CHEAP...and not use something like
WebSense or other filter products...(which charge quite a bit
more than I would rather spend)
You can take this long list of hostnames and put it in your
hosts file on your cache/proxy server which instead points them
at an internal server instead of the real ad-banner site.
Then you run a 10 line perl script on that server that acts
like a mini-web server, only it only returns and empty body.
It works really well for me, and it's ZERO cost and I have
never had the script fail. The only problem I have seen is
that some sites are now using ad-banner servers to provide
"functional" parts of their site, for instance graphic images
for navigation buttons. So in blocking the ad banner server
you break the ability to navigate, unless you know where to
click, hehe.

Subject: [FW1] Redirect traffic??
I want to allow the whole network (5000 comp) to go to
a site but I dont want the user to see the advertise
in this page (doubleclick.com , AOL, ) only the real
information.
Can I do this and how?
Or to use another computer like proxy redirect the
traffic to this computer and after that accept http
traffic on the firewall (port 80) only from this
computer?
Any help.
Thanks in advance.
P.S. Solaris 7 on Sparc, 4.1 SP3
