Pre-processing filters in Nexus Timestamp Server

This article describes the concept of pre-processing in a timestamp service in Nexus Timestamp Server. 

The pre-processing filter chain (1) is executed before selecting a policy (2) and running the filters associated to that policy (3). The filters in the pre-processing chain (1) are also, despite the name, executed after the policy filters have been executed. This second time the filters are run for post-processing purposes and in reverse order (4).
