Techniques for delivering current media content via content delivery networks

One or more non-transitory computer readable media including instructions that, when executed by one or more processors, cause the one or more processors to stream segments of a downloadable to a client device by performing the steps of:

• at a first point-in-time, receiving a first request for a first segment of the downloadable from the client device;
• computing a first cache key based on a first request Uniform Resource Locator (URL) included in the first request and a first version identifier associated with the downloadable;
• determining that no segment corresponding to the first cache key is stored in a first cache;
• transmitting a second request for the first segment to a different server;
• and
• upon receiving a first version of the first segment from the different server, transmitting a first response that includes the first version of the first segment to the client device.

A system comprising:

• one or more memories storing instructions;
• and
• one or more processors coupled to the one or more memories that, when executing the instructions, perform the steps of:
• at a first point-in-time, receiving a first request for a first object from a client device, wherein the first object is included in a first versionable group;
• computing a first cache key based on a first request Uniform Resource Locator (URL) included in the first request and a first version identifier associated with the first versionable group;
• determining that no object corresponding to the first cache key is stored in a first cache;
• transmitting a second request for the first object to a different server;
• and
• upon receiving a first version of the first object from the different server, transmitting a first response that includes the first version of the first object to the client device.
