Detailed Description
This is a simple filter based on the key/value pair stored in MDC.
The filter admits four options NeutralOnEmpty, MDCKeyToMatch MDCValueToMatch and AcceptOnMatch.
If NeutralOnEmpty is true and MDCKeyToMatch or MDCValueToMatch is empty then NEUTRAL is returned.
If NeutralOnEmpty is true and the string returned by event.getMDC(MDCKeyToMatch) is empty then NEUTRAL is returned.
If the string returned by event.getMDC(MDCKeyToMatch) matches MDCValueToMatch, then if AcceptOnMatch is true, ACCEPT is returned, and if AcceptOnMatch is false, DENY is returned.
If the string returned by event.getMDC(MDCKeyToMatch) does not match MDCValueToMatch, then if AcceptOnMatch is true, DENY is returned, and if AcceptOnMatch is false, ACCEPT is returned.
