Description
This article describes how to add multiple WCCP servers on FortiGate WCCP settings.

Solution
The requirement is to send the HTTPS, HTTP traffic to multiple WCCP servers, in case one server is not working other server would serve the traffic.
To enable multiple WCCP Serves, specify the both Servers IP's and subnet mask in WCCP settings:

Example (1).





If two servers are in the same subnet: (10.110.3.14/20,10.110.3.163/20).
Then the WCCP config is:
# config system wccp
    set server-list 10.110.0.0 255.255.240.0
end
Example (2).




If two servers are in different subnet: (10.110.3.14/20,20.110.3.163/20).
Then the WCCP config is:

# config system wccp
    set server-list 10.110.0.0 255.255.240.0 20.110.0.0 255.255.240.0
end
