Johan Acevedo commented on TS-974:
----------------------------------
Is there currently any cache software for http that manages to do this?
> TS should have a mode to hold partial objects in cache
> ------------------------------------------------------

> Key: TS-974
> URL: https://issues.apache.org/jira/browse/TS-974
> Project: Traffic Server
> Issue Type: Improvement
> Components: Cache
> Affects Versions: 3.0.1
> Reporter: William Bardwell
>
> For ATS to do an excelent job caching large files like video it would need to
> be able to hold partial objects for a large file. This could be done in a
> plugin or in the core. This would need to be integrated with the Range
> handling code to serve requests out of the partial objects and to get more
> parts of a file to satisfy a Range request.
> An intermediate step (also do-able in the core or in a plugin) would be to
> have some settings to let the Range handling code be able to trigger a full
> file download either asynchronously when a Range response indicates that the
> file isn't larger than some threshold, or synchronously when a Range request
> could reasonably be answered quickly from a full request. (Right now Range
> requests are tunneled if there is not full cached content as far as I can
> tell.)
