Abstract: A content delivery network (CDN) proxy (or, more generally, a server) that is content-aware is programmed to modify or augment a content object in such a manner that the content object, or elements thereof, is or are deliverable to a requesting client over a multi-stream, priority-enable connection. A representative application layer protocol that implements such delivery is SPDY. By virtue of its content-awareness, one or more elements of the content object may be delivered with prioritization so as to optimize “effective” page load time, namely, the time necessary for usable portions of the page to be loaded and rendered on the requesting client.

Abstract: A proxy system is provided to receive an HTTP request for content accessible over the Internet comprising: cache storage; and a computer system configured to implement, a CDN proxy module and an edge forward proxy module each having access to the cache storage to cache and to retrieve content; and a selector to select either the CDN proxy module or the edge forward proxy module depending upon contents of a header of the HTTP request received from the user device; an HTTP client to forward the request from the CDN proxy or from the edge forward proxy over the Internet to a server to serve the requested content.

Abstract: A system and a method for sharing a proxy between an ISP (Internet Service Provider) or other Internet point of presence, and a CDN (content delivery network).
