Upstream rules
You can switch between your server groups by creating upstream rules.
Overview
If a user has defined server groups and wants to use different groups depending upon different conditions then he can make use of Upstream Rules. For example, if a user wants its /API calls to be served by server-group "API" and console by "DEFAULT" then he can create a rule with a search pattern and search location as URL/Header/Cookie/Body/Arguments.
How to Use:

Go to WAF > Zones > Listeners > Rules > Upstream Rules
