Web Caching
Web Caching is available on the Qube 3 Professional Edition and Business
Edition only.
The Qube 3 offers a caching feature. When the caching feature is enabled, all
Web traffic (http://) routed through the Qube 3 is cached; the Qube 3 acts as a
caching proxy server for Web clients. This is known as “transparent caching”.
Alternatively, if network traffic is not routed through the Qube 3, clients can take
advantage of the Web Caching feature by configuring their Web browser to use
the IP address of the Qube 3 as its HTTP proxy and by setting the proxy port
number to 3128.
To enable the Web caching feature:
1. Select Administration > Web Services > Web Caching.
The Web Caching Settings table appears.
2. Click the Enable Caching check box.
3. Click Save.
✍
Note: The Web Caching feature on your Qube 3 relies on the Basic
Firewall feature to operate. If you enable the Web Caching feature,
the Basic Firewall feature is enabled automatically.
If you disable the Basic Firewall feature, the Web Caching feature
is still enabled but will not function. To ensure that the Web
Caching feature is functioning, re-enable the Basic Firewall feature.
For more information, see “Basic Firewall” on page 57.
