A web cache is a server or collection
of servers that stores copies of Internet content close to the LAN/user,
eliminates the need for each new request of the same content to traverse the
entire Internet, reduces bandwidth consumption, and
satisfies user requests for Internet content more quickly (see Figure 1). The
BayStack 910 web cache server provides this functionality via an affordable
BayStack chassis that's ideal for the SMB market segment.

Router Configuration
Not Required
The BayStack 910 web cache server requires minimal system and functional
administration. When adding the BayStack 910 to your LAN, there is
no need to configure your router,
no requirement for adding static
IP routes, no requirement to create
additional subnets, etc.
Browser Configuration
Not Required
The BayStack 910 web cache server
operates as a network layer cache server.
A network layer cache, often called a transparent cache server, intercepts HTTP
requests in a manner that is
transparent to the web browser. Thus, there is no requirement to configure
the client web browsers to point to a proxy server.
BayStack 910 Configuration Not Required
There is no requirement to assign an IP address to the BayStack 910 web
cache server. This eliminates the often-tedious tasks commonly required with
competitive products. These include attaching a serial cable to the unit and
using a terminal emulator to assign an IP address and
handle other configuration parameters.
Transparent Cache
Proxy server caches operate in combination and cooperation with the user's
web browser. Unfortunately, this requires that the web browser be configured to
redirect HTTP requests to the proxy server. The BayStack 910 is a network layer
cache, often called a "transparent" cache, which operates by
intercepting HTTP requests transparently to the web browser. If the content is
cached on the web server, this feature gets the web content to the user more
quickly. Thus, there is no need to modify the web browser.
Proprietary Routing Kernel
The BayStack 910 web cache server does
not use generic or freeware based routing software. Rather, it uses an amended
version of a proprietary routing kernel
to maximize throughput performance.
Proprietary Cache
Operating System
The BayStack 910 web cache server does not use a generic or freeware-based
cache operating system. Rather, a proprietary cache operating system has been
developed to maximize cache read/write performance.
Dual 10/100 Mbps
Ethernet Autosensing
To maximize data throughput and
prevent bottlenecks from occurring
within the product, the BayStack 910
web cache server is configured with two Autosensing 10/100 Mbps Ethernet
interfaces.
Smart Cache Automatic Content Refresh
The active refresh feature attempts
to keep the most frequently requested web entries fresh. Rather than wait for
a request for an entry, the BayStack 910 actively evaluates the elements in the
cache, tests them, and reloads them before they expire. You can choose the start
time, duration, and days of the week that active refreshing operates.
Browser-based Administration
Users can administer and configure
the BayStack 910 through their web browsers. As a result, there is no additional
management software to install and
no requirement to telnet to the unit.
Cache Hit Ratio Statistics
This feature displays the number of times the BayStack 910 web cache server
responded by returning information from the cache rather than a web server on
the Internet. A high percentage indicates that information is being served from
the web cache server, thus eliminating redundant downloading of data over your
Internet-access data line.
Data Rate Statistics
This displays the percentage of data your BayStack 910 web cache server
delivered from the cache as opposed to a web server on the Internet. The data
rate measures returned data, not sent data.
URL Logging
As clients on your LAN browse the Internet, the BayStack 910 administration
software displays the IP address or web site name of the requested sites, the
date and time of most recent access, and the number of times an entry has been
requested from the web site.
URL Blocking
The BayStack 910 web cache server allows the administrator to use URL
blocking. This feature sends an "access blocked" message to clients
requesting access to a restricted Internet web server.
Cookie Header Management
The BayStack 910 web cache server allows customers to improve their cache
hit ratios by managing cookies. Many web sites use cookies to inform a web
server about a user's identity and/or browsing habits. One result is that
entries with cookies attached are not cached,
preventing you from taking full advantage of the BayStack 910 web cache server.
Fortunately, you can often view a web site without having to accept cookies, so
you can block these cookies and still cache the entry without affecting the
data. By blocking cookies users can improve their cache hit ratio, as well as
their privacy. Some sites, however, require that you receive their cookies.
These include sites that use shopping carts or those that allow you to manage an
investment account
or portfolio. These types of web sites specifically require the use of cookies
for security and privacy purposes. The BayStack 910 web cache management tool
allows users to restrict cookie serving and returning on a per-web-site-basis.
The result is that the customer can
determine from which web sites to
allow cookies (non-cacheable content),
as well as from which sites to restrict cookies (thus caching the content). This
capability allows the customer to achieve the highest cache hit ratio possible.
HTTP 1.1 Compliance
The BayStack 910 supports persistent connections and cache control headers,
both of which are required for HTTP 1.1 compliance.
