Many thanks for the explanation 

There is a miss configuration in config file:

"cache deny all"

It's a shame...

Correct. To participate in that sharing, those concurrent clients must already 
have a lock on this entry. In other words, "concurrency" here is determined by 
having guaranteed access to the Store entry rather than just overlapping 
transaction lifetimes.

Yes, and this is not limited to the old entries in the disk cache. Entry 
"release" may happen even before the entry is earmarked for any of the caches, 
and the release affects both disk and memory caches.


If you want to figure out why this response is not being cached, you may need 
to figure out why the corresponding Store entry was marked for release. Look 
for releaseRequest lines in the debugging cache.log that match the same entry 
and try to determine why releaseRequest was called.

Alex.
