A browsing process is directed to the generation and management of a browse session at a network computing provider. A client computing device requests a remote browse session instance at a network computing provider. The browse session instance may correspond to requested network content. The network computing provider retrieves the requested content through an instantiated network browse session instance, and performs a first set of processing actions to generate a processing result. The processing result may be provided to the client computing device for display, including performing a second set of processing actions on the processing result at the client computing device. Metrics related to the retrieval, processing, and use of requested network content may be recorded and transmitted to a metric reporting server.
