1. A computer-implemented method for processing content at a client computing device, the method comprising: obtaining a set of content for processing on the client computing device, wherein the set of content includes executable code for causing the client computing device to generate a request to an identified service provider for a preload content list; generating, at the client computing device, a request for the preload content list responsive to the execution of the executable code; obtaining, from the identified service provider, the requested preload content list, wherein resources identified in the requested preload content list are unrelated at least in part to the set of content; and generating, at the client computing device, a request for preloading one or more of the resources identified in the preload content list at the client computing device; wherein the method is implemented by the client computing device configured with specific executable instructions.
