1. A method of routing resource access requests based upon a resource name, the method comprising:

  • receiving a name service reply for a resource;

    extracting a name for the resource from the name service reply;

    identifying that the resource name matches a redirection rule;

    deriving routing information for the resource from the name service reply in response to the resource name matching the redirection rule;

    identifying that the name service reply for the resource corresponds to at least one of a transfer control protocol synchronization (TCP SYNC) value, a universal datagram protocol (UDP) datagram, or an Internet control message protocol (ICMP) value;

    identifying that the incoming name service reply does not already have a corresponding entry in a virtual private network (VPN) look aside table;

    creating a routing entry in the VPN look aside table based on identifying that the VPN look aside table does not already have a corresponding entry that maps the name against the derived routing information in a look aside table based upon the name service reply;

    identifying that the incoming name service reply does not already have a corresponding entry in a system routing table; and

    creating an entry in the system routing table.
