Hello,
We are trying to cache some resources, but they respond in the header
with the attributes that prevent caching:
Content-Type: video/MP2T
*Expires: Thu, 01 Jan 1970 00:00:01 GMT*
*Cache-Control: no-cache*
Cache: HIT
X-Cached-Since: 2023-04-25T07:43:41+00:00
Thus, we see TCP_MISS in the logs.
Is it possible to configure squid in such a way that it ignores
*Cache-control=no-cache* and *Expires *attributes and takes responses
from the cache?
This is **not** uncacheable. As shown by "Cache: HIT" there was an
object found in the cache.
The "Expires" header is overridden by the existence of Cache-Control
header. So ignore that.
The Cache-Control:no-cache actually means Squid can cache the response,
but *must* contact the origin server before using a HIT.
For some reason the origin produced a newer version of the object thus
the log says "MISS".
