Re: mod_cache logging

Based on the caching decision made, the reason is also written to the subprocess environment under one the following four keys, as appropriate:

cache-hit

The response was served from cache.

cache-revalidate

The response was stale and was successfully revalidated, then served from cache.

cache-miss

The response was served from the upstream server.

cache-invalidate

The cached entity was invalidated by a request method other than GET or HEAD.

LogLevel debug

CustomLog logs/cached-requests.log common env=cache-hit

CustomLog logs/uncached-requests.log common env=cache-miss

CustomLog logs/revalidated-requests.log common env=cache-revalidate

CustomLog logs/invalidated-requests.log common env=cache-invalidate

LogFormat "%{cache-status}e " cachelog

CustomLog logs/cache.log cachelog

Personally never heard of the above cache-* env variables, only aware of no-cache one. I doubt they exist and need to be set in the config somehow in order for your logs to work since they are set as condition for them. Did yoy create the config your self or you copied it from somewhere? If that's the case probably the part about setting those env vars was omitted from the guide/example you followed.
