hi,

a proxy server/service normally uses acl's (access control lists) for users
and groups of users.  a proxy also can cache webpages for internal lan
users- that way, they don't have to go all the way to the net to get to
'yahoo's homepage' all the time.  a 'reverse proxy' is a proxy server
service that is listening on behalf of another service (ex. proxy's ext nic
interface listening on behalf of an internal http server)
