Abstract: In various embodiments, a live event caching application caches segments that are associated with live events. At a first point-in-time, the live event caching application stores a segment of a downloadable that is associated with a live event in a high priority list. At a second point-in-time, the live event caching application determines that the segment is at a tail of the high priority list, where the second point-in-time is subsequent to the first point-in-time. Upon determining that the segment is at the tail of the high priority list, further determining that an age of the segment is greater than a cutoff threshold. In response to determining that the age of the segment is greater than the cutoff threshold, moving the segment from the high priority list to a low priority list.

Abstract: In various embodiments, a caching application streams segments of a downloadable to a client device. At a first point-in-time, the caching application receives a first request for a first segment of the downloadable from the client device. The caching application computes a cache key based on a request Uniform Resource Locator included in the first request and a version identifier associated with the downloadable. The caching application determines that no segment corresponding to the cache key is stored in a cache. The caching application transmits a second request for the first segment to a different server. Upon receiving a first version of the first segment from the different server, the caching server transmits a response that includes the first version of the first segment to the client device.

Abstract: In various embodiments, a segment delivery application streams segments of downloadables to client devices. At a first point-in-time, the segment delivery application receives a request from a server for a segment of a downloadable. The segment delivery application determines that the segment is not available and that the segment is a next expected segment of the downloadable. At a second-point in time, the segment delivery application determines that the segment has become available. Upon determining that the segment has become available, the segment delivery application transmits to the server a response that includes the segment and corresponds to the request.
