For example, of how to actually do that, this website http://www.proxypacfiles.com/proxypac/index.php?option=com_content&view=article&id=54&Itemid=83 details the following: -- begin paste -- Blocking sites is also handy. This can be done for a number of reasons – Spyware/malware sites are very good examples Blocking these sites can be done very easily – Simply return a proxy value somewhere on a loopback address so that the requests never actually leave the local machine to take up network bandwidth. The only caveat with this is to ensure that your selection of port number isn’t actually listening on the PC which could odd behavior. if (dnsDomainIs(host, ".badspyware.com") || dnsDomainIs(host, ".worsespyware2.com")) { return "PROXY 127.0.0.1:48890"; } -- end paste -- I might add to that and actually run a simple webserver on the same machine that responds to any and all local connection attempts to it. It could respond with an error message saying why it failed, e.g. saying that only the following list of sites are allowed on this machine (and list your allowed sites on the page). -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
