: We solved that problem by transparent proxying. Its a switch in the
: Linux kernel (dunno if other os's support it) that lets you reroute
: packets for certain ports. So: Everything destined for port 80 -> proxy.

 We solved this too.. you just firewall all outgoing requests for port
 80 and soon everyone is using the proxy/cache!

 Seriously.. setting up a "autoconfig" script for netscape also
 makes a big difference.. then end users can just fire up
 netscape and away...

 We have hack DNS entries in our network so that the autoconfig
 option is "proxy/proxy.pac" and depending on where the client
 connects to depends on the machine that DNS identifies as
 "proxy.our.domain" and hence the local cache they connect
 to.

 We also have a script that takes all the ftp'd items from the
 cache objects list and add's them to our database of locally
 available ftp files... All these things save bandwidth :)
