Abstract
Streaming digital content synchronization techniques are described. A response is received to a request to stream the digital content. The response includes a time at which the digital content was last modified (e.g., a last-modified header) and a time at which the response was generated, e.g., a date header. An age is calculated by subtracting the time at which the digital content was last modified, e.g., the last-modified header, from the time at which the response was generated, e.g., the date header. An age describing an amount of time the response spent in one or more caches, if available, is added as part of this age. The time is determined by subtracting the age from a predefined setback time and the stream of the digital content is rendered based at least in part on the determined time.
