Apigee is a commercial product and, as such, we do not typically share explicit details on how certain features or capabilities are implemented.

With that said - is there a specific functional requirement that you have and are curious if the policy will achieve that? Are you running into an issue when testing the policy?

If you can provide more information and what you are looking to do, I'm sure we can provide some useful information.
