Web services across virtual routing and forwarding

A network communication device, comprising:

• one or more processing units having multiple cores;
• a first memory storing a local database representing state information about the computer device;
• and
• a second memory storing instructions, that when executed by the one or more processing units, cause the one or more processing units to provide a method to proxy request for multiple virtual routing and forwarding (VRF) instances on a single network communication device, the method comprising:
• instantiating a plurality of pairs of namespaces and instances of a Unix service, each of the plurality of pairs representing a proxy pair to support a single instance of a VRF, from a plurality of VRFs, on a network communication device;
• receiving a network request from a client device, the network request associated with a network address mapped to a first VRF from the plurality of VRFs;
• proxying the network request using a first proxy pair of namespace/service supporting the first VRF to a backend single instance of a proxy server, executing in an independent namespace associated with the backend single instance, using a local communication mechanism to communicate between the first proxy pair and the backend single instance;
• and
• providing the network request to a web service from the backend single instance of a proxy server on behalf of the first proxy pair.
