Effective Policies
When you publish an API to Mediator, CentraSite automatically validates the API's policy enforcement workflow to ensure that:
CentraSite will inform you of any violation, and you will need to correct the violations before publishing the API.
When you publish an API to Mediator, CentraSite combines the actions specified within the proxy API's enforcement definition, and generates what is called the effective policy for the API. For example, suppose your API is configured with two run-time actions: one that performs a logging action and another that performs a security action. When you publish the API, CentraSite automatically combines the two actions into one effective policy. The effective policy, which contains both the logging action and the security action, is the policy that CentraSite actually publishes to Mediator with the API.
When CentraSite generates the effective policy, it validates the resulting action list to ensure that:
*Any action that appears in a single message flow multiple times is allowed to appear multiple times.
For those actions that can appear in a message flow only once (for example, Evaluate IP Address), Mediator will choose only one, which might cause problems or unintended results.
*All action dependencies are properly met. That is, some actions must be used in conjunction with another particular action.
If the list contains conflicts or inconsistencies, CentraSite resolves them according to Policy Resolution Rules.
The effective policy that CentraSite produces for an API is contained in an object called a virtual service definition (VSD). The VSD is given to Mediator when you publish the API. After you publish an API to Mediator, you can view its VSD (and thus examine the effective policy that CentraSite generated for it) from the Mediator user interface.
The following table shows:
*Action is WS-Security Policy 1.2 compliant.
*Action dependencies, that is, whether an action must be used in conjunction with another particular action.
*Action exclusives, that is, whether an action cannot be used in conjunction with another particular action.
*Action occurrences, that is, whether an action can occur once or multiple times within a message flow stage. An action can occur multiple times in a policy if the selection criteria is combined using an AND operator (not an OR operator).
