Subject Re: Configure ATS reverse proxy with live HLS origin returning Cache-Control: no-cache

Hi, 
You have to  handle headers on origin servers. In addition to that there are some parameters
in records.config ingore no cache both client and servers.

Hi,
I am trying to configure ATS reverse proxy with a live HLS origin which
returns Cache-Control: no-cache on everything.
By default ATS doesn't cache anything because the origin server objects have
response headers with Cache-Control: no-cache (this is documented). 

The only way i found to get it to work was pinning the objects by adding the
following to cache.config:

url_regex=<path to origin> ttl-in-cache=10s

i choose 10 seconds because that is the target duration in the HLS playlist
(#EXT-X-TARGETDURATION)

But this seems like a very manual and verbose method , is there any better
way to configure live content from an origin that returns no-cache ?
Thanks.
