Cisco Cisco Web Security Appliance S380 User Guide

You can only specify one existing proxy during the System Setup Wizard. 
AsyncOS creates a proxy group with one proxy using the information you enter 
in the System Setup Wizard. You can specify additional proxies in the web 
interface after initial setup.

To create a proxy group:

Navigate to Network > Upstream Proxies, and click Add Group.

The Add Upstream Proxy Group page appears.

Enter a name for the proxy group in the Name field.

In the Proxy Servers section, define at least one external proxy.

In the Proxy Address field, enter the hostname or IP address of the proxy 
server.

In the Port field, enter the port number used to access the proxy.

In the Reconnection Attempts field, enter the number of times the Web Proxy 
should try to connect to the proxy server before ignoring it.

Optionally, you can define another proxy server by clicking Add Row.

In the Load Balancing field, choose the method the Web Proxy should use to 
distribute transactions to the proxies when the group contains multiple proxies.

For more information about the load balancing options, see 

.

In the Failure Handling field, choose how the Web Proxy should handle 
transactions when all proxies in the group fail.
