0 CDK SU Interceptor configuration 5.8.0


Interceptors can be defined to inject some post or pre-processing in the service processing.

Using interceptor is very sensitive and must be manipulated only by power users. A non properly coded interceptor engaged in a component can lead to uncontrolled behaviors, out of the standard process.

Example of an interceptor configuration:
