<1> Lazily get Filter that was registered as a Spring Bean.
For the example in <<servlet-delegatingfilterproxy-figure>> `delegate` is an instance of __Bean Filter~0~__.
<2> Delegate work to the Spring Bean.
Another benefit of `DelegatingFilterProxy` is that it allows delaying looking up `Filter` bean instances.
This is important because the container needs to register the `Filter` instances before the container can start up.
