20120150993ASSISTED DELIVERY OF CONTENT ADAPTED FOR A REQUESTING CLIENT - Disclosed herein are methods and apparatus facilitating delivery of web content that has adapted for particular client devices, such as mobile devices. Doing so may involve assisting a server without the adaptation logic necessary to deliver adapted content to a particular client device. For example, a given web server may adapt content and serve website content to a requesting client, but another server may take over when the client desires to make a purchase at the site. That other server, while perhaps qualified to process payment information, may not be able to provide adapted content. The content adaptation web server can assist that other server to do so. In other embodiments, such a content adapting server may provide such services to a range of other servers, and itself may not serve content directly to the client. The teachings herein may be implemented within a content delivery network.06-14-2012
20120203861METHODS AND SYSTEMS FOR DELIVERING CONTENT TO DIFFERENTIATED CLIENT DEVICES - Methods and systems are disclosed for delivery of tailored content to differentiated devices, such as desktop, mobile, and tablet devices, over a computer network. In one embodiment, a proxy cache server has a content cache for storing previously retrieved objects like web pages or multimedia files. For at least some objects, several versions are stored, each version representing an object suited for a given set of client device characteristics. A device-equivalency data structure maintained at the proxy facilitates a determination of whether such cached versions can be used to service a current request. The versions might represent, for example, modified versions created using, e.g., mobile device transcoding techniques, in response to prior requests. They may also represent a set of alternate content created by a content provider and available from an origin server. Such methods and systems may be implemented in a distributed computing networks, e.g., a content delivery network.08-09-2012
20130219024METHODS AND APPARATUS FOR ACCELERATING CONTENT AUTHORED FOR MULTIPLE DEVICES - Disclosed herein are systems, methods, and apparatus for improving the delivery of web content that has been authored for multiple devices. In certain embodiments, an intermediary device such as a proxy server determines the characteristics of a client device requesting multi-device content, obtains and examines the multi-device content, and in view of the particular requesting client device removes portions that are irrelevant for that device. Doing so can accelerate delivery of the content by reducing payload and relieving the client device of the processing burden associated with parsing the content to make that determination itself, among other things.08-22-2013

20150100660SYSTEMS AND METHODS FOR CACHING CONTENT WITH NOTIFICATION-BASED INVALIDATION - 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.04-09-2015
20150100664SYSTEMS AND METHODS FOR CACHING CONTENT WITH NOTIFICATION-BASED INVALIDATION WITH EXTENSION TO CLIENTS - 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. This caching and invalidation model can be extended out to clients, such that clients may be notified of invalid data and obtain timely updates.04-09-2015
20150207897SYSTEMS AND METHODS FOR CONTROLLING CACHEABILITY AND PRIVACY OF OBJECTS - 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.07-23-2015
20150281331SERVER INITIATED MULTIPATH CONTENT DELIVERY - Described herein are—among other things—systems, methods, and apparatus for accelerating and increasing the reliability of content delivery by serving objects redundantly over multiple paths from multiple servers. In preferred embodiments, the decision to use such multipath delivery is made on the server side. A content server can modify or generate a given web page so as to invoke multipath, e.g., by injecting markup language directives and/or script instructions that will cause the client device to make multiple requests for a given object on the page. Preferably the multiple requests are made to separate content servers in separate points of presence. The teachings hereof may be advantageously implemented, without limitation, in intermediary servers such as caching proxy servers and/or in origin servers.10-01-2015
20150310126CREATION AND DELIVERY OF PRE-RENDERED WEB PAGES FOR ACCELERATED BROWSING - 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.10-29-2015

The checkerboard array comprises alternating phase-shift regions R that have a relative phase difference of 180 degrees. The sub-resolution assist phase regions R′ reside adjacent corresponding phase-shift regions R and have a relative phase difference of 180 degrees thereto. The sub-resolution assist phase regions R′ are configured to mitigate undesirable edge effects when photolithographically forming photoresist features. Method of forming LEDs using the phase-shift mask are also disclosed.06-21-2012
