As traffic across the Internet gateway and the wide area network grows at
exponential rates, so does network congestion. This situation presents
numerous challenges to network administrators, who need to manage network
traffic, prevent access to inappropriate content, protect their network
from viruses, and selectively allow encrypted traffic in and out.
Netscape Proxy Server software is a powerful system for replicating and filtering
Web content. It significantly reduces network congestion, controls
access to network resources, and facilitates encrypted traffic, all while
maintaining low cost of ownership.
Proxy Server's efficient replication model requests data only when an end user
needs it, dramatically reducing response times for clients accessing the
Internet or an intranet and significantly lowering network costs.
Replication-on-demand intelligently caches frequently accessed documents
to conserve network bandwidth. Netscape Proxy Server maintains version
control and document expiration information, so it can deliver fresh
content. Replication-on-command also allows specific documents,
directories, and sites to be downloaded in advance over the Internet or
an intranet. This allows a corporation, for example, to replicate content
to remote offices efficiently and transparently.
Proxy Server's fine-grained controls limit access to documents,
directories, or sites, and includes categorized URL filtering services.
It regulates access to resources based on user name and password
combinations or on IP, host, or DNS wildcard expressions. Netscape Proxy
Server also provides virus detection and filters by content type at the Internet gateway.
Scalability and high performance make Netscape's Proxy Server an optimal
solution for seamless communication across an intranet or the Internet.
Support for the Netscape Server Plug-in API allows incorporation of third-party
technologies and customized in-house solutions.
Netscape Proxy Server operates on a high-performance HTTP engine. It
supports HTTP extensions for byte ranges and "keep-alives," which improve
performance in returning complex documents. Netscape Proxy Server
architecture allows efficient caching of up to 128GB of data and 70
million unique URLs.
Netscape Proxy Server makes it easy for administrators to manage
intelligent networks of proxy servers. They can chain proxies for hierarchical caching using
proxy routing and the Automatic Proxy
Configuration (APC) feature of Netscape Communicator.
APC also permits modifications to the proxy
infrastructure without touching client software on each desktop. Netscape
Proxy Server also uses Netscape Communicator's intuitive interface for
encrypted administration from a variety of locations on the network, and supports SNMP
versions 1 and 2.
Networks are only as strong as their weakest link, which is often the
gateway. Netscape Proxy Server enhances network security by providing a
network control point for Internet traffic. It controls access to an
external network, provides access through a firewall, and compiles
logs of all transactions. Secure reverse proxying also allows
Netscape Proxy Server to act as an intermediary for all clients
connecting to a remote web server, accepting encrypted traffic on behalf
of a web server protected behind a firewall. Netscape Proxy Server also
provides added network reliability through automated response or fail-over
to a secondary proxy when the network or a remote web server is
Netscape Proxy Server provides faster, more reliable network performance

Provides efficient, transparent replication-on-demand of web documents,
automatically routing HTTP requests to Netscape Proxy Server and returning
current documents from the cache.
Downloads documents or entire sites to ensure that the busiest sites are cached
and available. Replication-on-command allows content to be seamlessly
replicated to remote sites. It also refreshes all data in the cache at specified intervals
to ensure freshness and availability for periods of heavy use.
Provides remote sites with an accurate "hit count," even if documents are
returned from the cache.
Supports proxy chaining for building hierarchical caches that improve performance on internal networks.
Controls access to network resources by granting or denying access based on user
name and password; named groups; or IP-, DNS-, and host-based wildcard expressions.
Scans incoming files for viruses, over both HTTP and FTP, and alerts
administrators when a virus has been detected. Includes access to regular
Provides content filtering for URL's, MIME types, and HTML tags.
Netscape Communicator's Automatic Proxy
Configuration makes the proxy configuration transparent to end users.
Provides a consistent, cross-platform, easy-to-use administration
environment through HTML forms. Encrypts communication using secure
sockets layer (SSL) for protected remote administration
Supports SNMP versions 1 and 2 for standards-basic, remote monitoring and
Enables administrators to tune configurations without major planning
efforts or high-risk implementations. Rollback to the previous stable
configuration is available.
Delivers maximum throughput and supports new performance standards, such
as HTTP byte-range extensions and keep-alives.
Efficiently caches up to 128GB, and can handle more than 70 million unique
URLs in order to maximize the cache hit rate.
Encrypts communications using SSL 3.0, the latest version of the widely
accepted Internet security standard.
Serves as an intermediary for all clients connecting to a remote web
server. Secure reverse proxying provides an additional barrier for web
servers and applications behind firewalls by accepting an SSL session from
the client and creating a new SSL session with the server.
Logs all HTTP, FTP, and Gopher transactions in common or extended log
formats, including referrer field, user agent, and transaction
Responds automatically if the network is unavailable, notifying clients.
Routes an HTTP request to a secondary proxy if the primary proxy is
