Network Interfaces
IP Address Versions
In Standard mode, Cisco Web Security Appliance supports IPv4 and IPv6 addresses in most cases.
Note
In Cloud Connector mode, Cisco Web Security Appliance supports IPv4 only.
Load Balancing
The strategy that the web proxy uses to load balance requests between 
multiple upstream proxies. Choose from:
None (failover). The Web Proxy directs transactions to one external 
proxy in the group. It tries to connect to the proxies in the order they are 
listed. If one proxy cannot be reached, the Web Proxy attempts to 
connect to the next one in the list.
Fewest connections. The Web Proxy keeps track of how many active 
requests are with the different proxies in the group and it directs a 
transaction to the proxy currently servicing the fewest number of 
connections.
Hash based. Least recently used. The Web Proxy directs a transaction 
to the proxy that least recently received a transaction if all proxies are 
currently active. This setting is similar to round robin except the Web 
Proxy also takes into account transactions a proxy has received by being 
a member in a different proxy group. That is, if a proxy is listed in 
multiple proxy groups, the “least recently used” option is less likely to 
overburden that proxy.
Round robin. The Web Proxy cycles transactions equally among all 
proxies in the group in the listed order.
Note
The Load Balancing option is dimmed until two or more proxies 
have been defined. 
Failure Handling
Specifies the default action to take if all proxies in this group fail. Choose 
from:
Connect directly. Send the requests directly to their destination servers.
Drop requests. Discard the requests without forwarding them.
