ICAP Load Balancing

ICAP load balancing can be configure the balance the traffic load to ICAP servers based on assigned weights, send new sessions to the ICAP server with the lowest session count, or send new sessions to the active ICAP server with the highest weight.

By default, ICAP is not visible in the tree menu in the GUI. To make it visible, go to System > Feature Visibility and enable it. See Feature Visibility for more information.

   • Weighted: Balance the traffic load to ICAP servers based on the assigned weights.

   • Least Session: Send new sessions to the ICAP server with the lowest session count.

   • Active Passive: Send new sessions to the active ICAP server with the highest weight.

4. To create a server list for load balancing:

   1. Click Create New in the Set up Server List for Load Balance table.

   2. Select or create a remote server. See ICAP Remote Server for information.
