Layer 7 Load Balancing
This example shows how to make load-balancing decisions based on Layer 7 information. In this case,
the CSM terminates the TCP connection, buffers the request, and parses it to see if the request matches
the policy conditions. When a load-balancing decision is made, the CSM opens the connection to the
selected server and splices the two flows together.
The configuration in this example requires the use of maps and policies. A policy is a list of conditions
and actions that are taken if all the conditions are true.
