Abstract: There is disclosed herein computer implemented methods of cache key generation including receiving from a user a request for content; wherein the request comprises one or more of opening a browser software tab or window, launching a software application, activating a hyperlink; wherein the request causes an electronic communications network connection to be established and/or an HTTP request made; and wherein, the surrogate passes the request to an origin.

Abstract: Described herein are, among other things, systems and methods for generating and using manifests in delivering web content, and for using such manifests for prefetching. Manual and automated generation of manifests are disclosed. Such manifests preferably have placeholders or variables that can be populated at the time of the client request, based on data known from the request and other contextual information. Preferably though without limitation an intermediary device such as a proxy server, which may be part of content delivery network (CDN), performs the function of populating the manifest given a client request for a page. An intermediary or other computer device with a populated manifest can utilize that completed manifest to make anticipatory forward requests to an origin to obtain web resources specified on the manifest, before receiving the client's requests for them. In this way, many kinds of content may be prefetched based on the manifest.
