[Bug 48241] New: mod_cache is missing hit/miss indication to the error log/env vars

https://issues.apache.org/bugzilla/show_bug.cgi?id=48241

Summary: mod_cache is missing hit/miss indication to the error
log/env vars
Product: Apache httpd-2
Version: 2.3-HEAD
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P2
Component: mod_cache
AssignedTo: bugs [at] httpd
ReportedBy: wrowe [at] apache


Read an inquiry about logging cache hits and misses in the access log (or
control what is logged in the access log using an env test)

mod_cache should record a 'cache-hit' flag on success or failure if caching was
configured. E.g. '1' is a hit, '0' is a failure, uninitialized was no attempt.

What makes this more severe is that nothing about the cache behavior is
captured in the debug-level error log, which means there is no guidance of
whether the cache attempted a lookup and encountered success or failure (unless
there is a hard error about accessing the respective cache repository).

Finally there is no debug-level error logging to indicate an element was added
to the cache (or not added, and perhaps what header circumvented this), again a
serious omission for diagnostics of cache configuration.
