Proxy Forwarding
If your organization uses a proxy server such as Blue Coat or Netbox Blue to
control Internet access, use this page to configure proxy forwarding on the Array.
About Proxy Forwarding
Figure 115. Proxy Forwarding Example
When you configure proxy forwarding settings on the Array, it forwards each
HTTP request to the proxy server (for example, Blue Coat) at the specified URL,
which checks if the policies that you have set up on the server are satisfied. If so,
the proxy server sends the request on to the desired web site. An example is
shown in Figure 115. The user of the laptop tries to open Facebook on a browser.
The Array forwards this request to the proxy server that you have specified, after
adding a prefix with the user’s ID and the SSID (the SSID serves as a user group;
for unauthenticated clients, the MAC address serves as the user name). The proxy
server checks whether its configured policies permit this access for this user and
SSID. If so, the frame is forwarded to the desired web site.

Some smaller Arrays/APs have less memory (XR-500/1000 Series and
XR-620) and are not able to run all ArrayOS features at the same time. You
will receive an error message if you attempt to configure a feature when there
is not enough memory left.
