    Abstract: Systems and methods for processing a DNS query to identify and implement pre-processing information by a DNS server component in anticipation of a corresponding content request from a client computing device are provided. The pre-processing information can correspond to identification of content to be preloaded or other actions to be implemented by one or more computing devices in association with an anticipated client content request. Based on identification of the content or future actions, a DNS server component can provide the pre-processing information to one or more computing devices, such as computing devices of a CDN service provider and/or an original content provider, in advance of a corresponding request for content from the client computing device in order to improve performance associated with responding to the client request.

    Abstract: An edge system receives requests from user devices to retrieves files from an origin server. Instead of retrieving the files as fast as possible, the edge system throttles the retrieval of files to a rate that just exceeds the speed at which the file is played by a browser or media player. The edge system determines an appropriate retrieval rate based on the contents of the file itself. For example, a manifest file associated with the file can indicate a time it takes to play back content and a bitrate of the content. Thus, the edge server can use this information to retrieve a file from an origin server at a rate that is just fast enough to minimize playback interruption. The retrieval rate determined by the edge server therefore does not rely on how fast or slow the user device retrieves the file from the edge server.

    Abstract: Systems and methods are described to enable delivery of streaming content while inhibiting or preventing removal, blocking, or skipping of portions within that streaming content. A content delivery system can generate a manifest indicating content portions that form the streaming content. Each content portion can be identified in the manifest using a concealed identifier, which conceals the actual identifier of the content portion from the client to inhibit or prevent the client from automatically removing or modifying the content portion. On receiving a request for a content portion, the content delivery system can convert the concealed identifier into the actual identifier, and return the appropriate content portion to the client. In some instances, the specific identifiers included within a concealed manifest may be modified or adapted based on monitoring information of the client device, to ensure clients view given portions of streaming content.
