摘要： Among other things, this document describes systems, devices, and methods for improving the delivery and performance of web pages authored to produce virtual reality (VR) or augmented reality (AR) experiences. In some embodiments, such web pages are analyzed. This analysis may be initiated at the request of a content server that receives a client request for the HTML. The analysis may involve, asynchronous to the client request, loading the page into a non-user-facing browser environment and allowing the VR or AR scene to execute, even including executing animation routines for a predetermined period of time. Certain characteristics of the scene and of objects are thereby captured. Based on this information, an object list ordered by loading priority is prepared. Consulting this information in response to subsequent requests for the page, a content server can implement server push, early hints and/or other delivery enhancements.

摘要： A server in a content delivery network (CDN) can examine API traffic and extract therefrom content that can be optimized before it is served to a client. The server can apply content location instructions to a given API message to find such content therein. Upon finding an instance of such content, the server can verify the identity of the content by applying a set of content verification instructions. If verification succeeds, the server can retrieve an optimized version of the identified content and swap it into the API message for the original version. If an optimized version is not available, the server can initiate an optimization process so that next time the optimized version will be available. In some embodiments, an analysis service can assist by observing traffic from an API endpoint over time, detecting the format of API messages and producing the content location and verification instructions.

摘要： Described herein are systems, devices, and methods for content delivery on the Internet. In certain non-limiting embodiments, a caching model is provided that can support caching for indefinite time periods, potentially with infinite or relatively long time-to-live values, yet provide prompt updates when the underlying origin content changes. In one approach, an origin server can annotate its responses to content requests with tokens, e.g., placing them in an appended HTTP header or otherwise. The tokens can drive the process of caching, and can be used as handles for later invalidating the responses within caching proxy servers delivering the content. Tokens may be used to represent a variety of kinds of dependencies expressed in the response, including without limitation data, data ranges, or logic that was a basis for the construction of the response.

摘要： Described herein are systems, devices, and methods for content delivery on the Internet. In certain non-limiting embodiments, a caching model is provided that can support caching for indefinite time periods, potentially with infinite or relatively long time-to-live values, yet provide prompt updates when the underlying origin content changes. Origin-generated tokens can drive the process of caching, and can be used as handles for later invalidating origin responses within caching proxy servers delivering the content. Tokens can also be used to control object caching behavior at a server, and in particular to control how an object is indexed in cache and who it may be served to. Tokens may indicate, for example, that responses to certain requested URL paths are public, or may be used to map user-id in a client request to a group for purposes of locating valid cache entries in response to subsequent client requests.

摘要： The process of rendering web pages can be significantly improved with a content delivery system that pre-renders web content for a client device. A web page “program” can be pre-executed and the result delivered to a requesting client device, rather than or before sending a traditional set of web page components, such as a markup language document, cascading style sheets, embedded objects. This pre-execution can relieve the client device of the burden of rendering the web page, saving resources and decreasing latency before the web page is ready, and can reduce the number of network requests that the client device must make before being able to display the page. Disclosed herein are methods, systems, and devices for creating and delivering pre-rendered web pages for accelerated browsing.

摘要： Among other things, this document describes systems, devices, and methods for using TLS session resumption tickets to store and manage information about objects that a server or a set of servers has previously delivered to a client and therefore that the client is likely to have in client-side cache. When communicated to a server later, this information can be used to drive server decisions about whether to push an object to a client, e.g., using an HTTP/2 server push function or the like, or whether to send an early hint to the client about an object.
