Thanks for the reply

 

So presumably there is no way to do this with ats?

Sounds like you're interested in stale-while-revalidate [1].  It does
not appear to be supported in ATS, but is implemented in Squid [2] and
works quite well.

Hi Guys,

 

Is it possible to get ATS on stale hit to serve from cache and refresh
the cache in the background?


The use case is when we are experiencing issues with the origin server I
would like to serve stale content (compared to nothing) and then get ats
to refresh it in the background instead of holding traffic up.

 

Thanks


Mav
