mod_cache with CacheStaleOnError returns 503 for proxy error instead of returning stale entry from cache
Issue
- We us mod_cache on httpd.
CacheStaleOnErrorshould default toOnand we explicitly set it toOn, but it does not seem to work since httpd is returning 502 or 503 responses in the event of a failed proxy attempt instead of serving the stale cache content
Environment
