hi Igor,
Do I understand correctly the proxy_cache_use_stale directive:
proxy_cache_use_stale error timeout invalid_header http_500;
If cache is still valid {
serve content from cache
} else {
Ask fresh data to the backend
if connection status IS IN (proxy_cache_use_stale parameters) {
serve content from cache
} else {
act as normal
}
}
thx
