{anchor:cdk-su-interceptor-cfg}
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:
