1. A method for communicating feedback to enforce security policies on transport of content, comprising: receiving, from a Port Control Protocol (PCP) client of a first device at a PCP server of a network, a PCP Map request comprising a query whether the PCP client can bundle a plurality of streams into a flow according to a 5-tuple comprising source Internet Protocol (IP) address, destination IP address, protocol, source port number, and destination port number; determining, by the PCP server using a policy application, whether at least one of the plurality of streams is to be provided to a security application through a relay element; in response to determining the PCP client must transmit at least one of the plurality of streams separately from the rest of the plurality of streams, transmitting, from the PCP server to the PCP client, a first PCP Option response indicating to the PCP client that bundling is not allowed for the at least one of the plurality of streams and the at least one of the plurality of streams is to be provided to the security application through a relay element; determining, by the PCP server using the policy application, whether the PCP client is allowed to bundle the rest of the plurality of streams into the flow and the network is configured to classify traffic on a per-packet basis; and in response to determining the PCP client is allowed to bundle the rest of the plurality of streams into the flow and the network is configured to classify traffic on a per-packet basis, transmitting, from the PCP server to the PCP client, a second PCP Option response to the query indicating to the PCP client that bundling for the rest of the plurality of streams is allowed.
