According to the Manage | Citrix Virtual Apps and Desktops 7 2308 document, the order of evaluation of rewrite policies is determined by the following factors:
The priority of the policy. A lower number indicates a higher priority.
The bind point of the policy. A global policy has a lower priority than a policy bound to a specific virtual server.
The type of the policy. A request policy has a higher priority than a response policy.
In this scenario, the policies are all bound to the same virtual server and have the same type (response). Therefore, the order of evaluation is based on the priority of the policy. The policy with the lowest priority number (POL_2) is evaluated first, followed by the policy with the next lowest priority number (POL_3), and so on. The policy with the highest priority number (POL_1) is evaluated last. Therefore, the correct answer is C.
