Are you saying that new objects are not written to disk until they
expire from the memory cache? The implication would presumably be that
some objects are lost when squid shuts down.
Yes. There is some time spent saving as many as possible to disk during
the shutdown_timeout, but this rarely gets it all due to being
configured too short.
Consider though that caching is an entirely optional to start with.
Things in the cache can be re-fetched as needed from the network. So
there is no actual loss.
