How to give access to one site, Not the whole internet

[Sina]

Here is the chanllenge:

Users at my work place don't have internet. We are not allowed to provide internet for them.

But on the other hand, I have to give access to one site( one page where they can search for phone numbers) on the internet, without giving them access to the entire internet.

The site out there, call it "SiteA". The users should be able to go to this site and input data to search for phone numbers and such.

How can this be achived using Linux Apache and proxy server or IP forwarding.

Is something like this possible.?
Thank you all

u need Squid.. check the FreeBSD ports collection, u will most certainly find Squid.. Squid is an HTTP proxy cache server.. u can use it's access list system to specify where users can and can't connect to..

it's full ops is beyond the scope of this post, but there is extensive info on Squid..

http://www.squid-cache.org

is a good place to start..

good luck..
