The WXA series appliance offers WFS Acceleration for Unsigned SMB and Signed SMB traffic.
In a network that supports unsigned SMB traffic, the WFS Acceleration service configuration is
greatly simplified. The reason for this is Unsigned SMB traffic does not have a security layer,
so the WXA series appliance can intercept the traffic without joining the domain, eliminating the
need to configure custom zones, configuring reverse lookup, and add file shares. In a network
that supports SMB signing, it is required that the WXA series appliance join the domain, due to
the presence of a security layer in Signed SMB traffic. Although this type of configuration is
more complex than unsigned SMB, it offers a more granular configuration of the WFS
Acceleration service. Supporting SMB signing provides the option to configure WFS
Acceleration in a Basic or Advanced configuration modes.
Refer to Configuring WFS Acceleration on page 97, for details on how to configure WFS
Acceleration.
Web Cache
The Web Cache feature stores copies of Web pages passing through the network that are
frequently and recently requested. So when a user requests one of these Web pages, it is
retrieved from the local web cache instead of the Internet, saving bandwidth and response time.
Minimal, Moderate, and Aggressive caching strategies are available, these determine which
objects are placed into the web cache and how long they stay there.
Refer to Configuring the Web Cache on page 131, for details on configuring the web cache.
