1. A computer-implemented method comprising: obtaining, from a client computing device by a service provider, a protocol-based request for a resource, the protocol-based request for a resource associated with an embedded resource identifier; transmitting, by the service provider, a request from the first separately identifiable component of the service provider to a second separately identifiable component of the service provider to initiate protocol-based communications with the client computing device; transmitting, to the client computing device by the service provider, responsive protocol-based request information from the first separately identifiable component and additional protocol-based request information from the second separately identifiable component responsive to the request from the first separately identifiable component of the service provider; and determining, by the service provider, metric information associated with the responsive protocol-based request information and the additional protocol-based request information, the metric information associated with communications between the client computing device and the first and second separately identifiable components of the service provider.
