A browsing process is directed to the generation and management of a browse session at a network computing and storage provider. A client computing device requests a remote browse session instance at a network computing and storage provider. The browse session instance may correspond to requested network content. The network computing and storage provider determines a browse configuration. The browse configuration may identify a communication protocol and various processing actions. The network computing and storage 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.
