Action hook. Actions represent the callback mechanism used by
coyote servlet containers to request operations on the coyote connectors.
Some standard actions are defined in ActionCode, however custom
actions are permitted.
The param object can be used to pass and return informations related with the
action.
This interface is typically implemented by ProtocolHandlers, and the param
is usually a Request or Response object.
