A framework supporting content delivery and comprising a plurality of devices, each device configured to run at least one content delivery (CD) service of a plurality of CD services, wherein the plurality of CD services comprise: collector services, reducer services, origin services, and control services; and wherein at least some of the plurality of devices run origin services, and wherein the origin services running on the at least some of the plurality of devices comprise at least one origin services network. At least one origin service is configured to provide persistent origin that is locally and/or globally addressable.

Content Delivery Framework having Origin Services

Systems, apparatus, and methods for implementing enterprise level social and business information networking are provided. Users can receive relevant information about a database system and its users at an appropriate time. Users can then use this relevant information to reduce errors and limit redundant efforts. For example, an update of a record in the database can be identified, and a story created automatically about the update and sent to the users that are following the record. Other events besides updating of records can also be tracked. A variety of enhanced features and functions are also presented in the context of an enterprise level social and business information networking environment.

Enhanced chat features for an enterprise level business information networking environment

A computer-implemented method includes providing, at a first time and to a first group of CD services in a CDN, invalidation information relating to at least one resource; and providing the invalidation information, at a second time distinct from the first time and to a second group of CD services in the CDN, the second group of CD services being substantially distinct from the first group of CD services.

Invalidation sequencing in a content delivery framework

A computer-implemented method operable in a content delivery network (CDN), includes receiving a request a service in said CDN; determining a particular classification of an Internet Protocol (IP) address associated with said request, said determining using a first function that maps IP addresses to one or more classifications, said particular classification being one of said one or more classifications; and processing said request based on said particular classification of said IP address associated with said request. A location-specific response to a request may be based on a geographic location associated with said IP address associated with said request.

Geographic Location Determination in a Content Delivery Framework

A computer-implemented method includes receiving, at a service running on the hardware, invalidation information relating to one or more resources; and determining whether the invalidation information relates to any resources currently stored on the service. Based on the determining, when the invalidation information relates to at least one resource not currently cached on the service, maintaining on the service at least some of the invalidation information; and using the maintained invalidation information on the service to prevent subsequent use of a version of at least one resource not currently stored on the service.

Invalidation systems, methods, and devices

Examples of systems and methods for context based virtual area creation are described. Some examples provide a quick and easy way for users to wrap virtual areas around contexts of interest. Examples of such contexts may be defined in terms of one or more of content, people, and real-world location. The virtual areas support realtime communications between communicants (e.g., one or more of text chat, voice, video, application sharing, and file sharing) and provide a persistent historical repository for interactions in the virtual area. Summaries of activities and other events in virtual areas typically are published in realtime so that other communicants can readily obtain a quick summary of the activities occurring in a particular context and decide whether or not to join or otherwise participate in those activities.
