Caching Web documents naturally poses problems as well as solves them. In fact, the Netscape Proxy Server sports a very sophisticated cache refresh management scheme which is entirely user-configurable. The Proxy Server uses dynamic process management with the result that, overall, it achieves unmatched performance at serving Web documents. A variety of security features are part and parcel of the Proxy Server. First and foremost, the nature of the caching activity of the Proxy Server conceals the number of users within an organisation, their IP addresses, and the true extent of their Internet activity.
Internet accesses require the entry of a user ID and password.
The Netscape Proxy Server has other applications in addition to interfacing between a LAN and the Internet. A standard configuration would have 32MB RAM and between 1 and 6GB disk storage.
