Opening a new thread on the rules engine. Please keep responses in the email 
thread (vs. wiki). I will summarize once we conclude debate.


Rules Engine<https://cwiki.apache.org/#ConfigurationManagement-Rules_Engine>

  *   The rules engine is a part of the generic configuration concept but 
separates out trigger/action type configurations from parameter type 
configurations
  *   It allows non-technical users access to powerful customizations that can 
be validated before use and implemented in non-blocking LUA co-routines
  *   Service Parameters are stored in the config database as per usual 
operation
     *   Parameter Example:
        *   Serivce is Active or Non-Active
        *   Service considers Query Strings in URLs or Does Note
  *   Service Rules are stored in a specially formatted data table
     *   Rules Example:
     *
Trigger

Action

Request to Origin

Sign URL using AWS v4 Signature and Key

URL format regex

Strip content from URL and add to header

Failure to connect to origin

Add cache control header to 502 response with 10 second value


     *
  *   Rules Engine Provides
     *   List of Available Triggers
     *   List of Available Actions
     *   List of Required Parameters for Each Trigger / Action
  *   Rules for ATS and NGINX can be implemented with LUA Plugins to the C/C++ 
Code using LUA Scripting
  *   We can also potentially offer raw script fields for advanced users like 
CDN Owners
  *   Rules are generic and are interpreted in similar fashion to generic 
configuration parameters
  *   Rules engine builds in validation rules to ensure non-breaking changes
