2.2.2 Processing Policies, Rules, and Actions
Each service that you configure will have exactly one Processing Policy. The processing policy defines
what should happen when a message arrives from either the client (request), or the server (response).
A processing policy is comprised of one or more Processing Rules. A processing rule always begins with
a Match Action, followed by one or more Processing Actions. Processing rules are identified as either
request, response, both, or error types. A processing rule that is indicated as a request rule will be
ignored during response processing. A processing rule that is identified as both will be evaluated for both
requests and responses. Error rules are executed only when an error occurs during processing.

The Match Action references a Match Rule that contains one or more matching criteria (or expressions)
that are evaluated to determine whether or not to execute the remaining actions in the processing rule.
When more than one match expression is defined, the match rule can specify whether to combine them
with Boolean AND or OR semantics. When the match rule is configured to use OR, only one of the match
expressions must be True; when AND is specified, all expressions must evaluate to True.
