Abstract
Content (e.g., files such as streaming audio or video) may be efficiently cached and delivered in a network. In one implementation, a method may include receiving, from a requesting computing device, a request for a segment of a content item, the request indicating one or more positions in the content item that define the segment of the content item. The method may further include determining a second segment of the content item, different from the first segment of the content item, in which the second segment of the content item is aligned so that an end position of the second segment of the content item matches an end position of one of a number of predetermined segments for the content item. The method may further include obtaining the second segment of the content item and transmitting the obtained second segment of the content item to the requesting computing device.
