Conditional routing based on backend status

Products

• CA API Gateway
• API SECURITY

Issue/Introduction

When the API Gateway is used as a reverse proxy, is it possible to exclude specific backend servers based on their status? (fallback operation)

Environment

Release : 9.0

Component : API GATEWAY

Resolution

There isn't a single assertion which can be working as a reverse proxy, doing health check of backend servers, and continuing fallback operation by excluding unhealthy backends.
It may be possible to create a set of policies for the purpose but designing policies is out of the scope of Technical Support.
