});Boomcatch implements four extension points to control how beacon requests are handled: validators, filters, mappers and forwarders. These extension points are invoked as a pipeline when a beacon request is received.
Several extensions are shipped as part of Boomcatch, or you can implement your own custom extensions.
You can read more details in the documentation about extensions.
