-----------------------------------------------

What is the current development state for this issue? Any real advance about coding or there is only discussion about how to implementa it?
I read that it is partially complete: (https://cwiki.apache.org/confluence/display/TS/Cache+Projects)
I need this funcionality so I want to finish it.
How van I get

> 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.)
