Abstract: Embodiments are directed towards exposing access to network metrics to a late binding user customized set of computer instructions within a traffic manager device (TMD) for use in managing a request for a resource. In one embodiment, the TMD may be interposed between client devices and a plurality of network devices. Request specific data is extracted from a client request received by the user's instructions. Various network metrics about the network devices are provided to the user's instructions to selectively provide the request from the client device to a network device. In one embodiment, an election hash is described as an action performed by the user's instructions.
