-- Gets an origin request policy, including the following metadata:
--
-- -   The policy\'s identifier.
--
-- -   The date and time when the policy was last modified.
--
-- To get an origin request policy, you must provide the policy\'s
-- identifier. If the origin request policy is attached to a
-- distribution\'s cache behavior, you can get the policy\'s identifier
-- using @ListDistributions@ or @GetDistribution@. If the origin request
-- policy is not attached to a cache behavior, you can get the identifier
-- using @ListOriginRequestPolicies@.
