I used this config in my virtual host in Apache 2.4 on Ubuntu 16:
<VirtualHost> ... CacheQuickHandler on CacheLock on CacheLockPath /tmp/mod_cache-lock CacheLockMaxAge 5 CacheIgnoreHeaders Set-Cookie <Location /> CacheEnable disk CacheHeader on CacheDefaultExpire 800 CacheMaxExpire 64000 CacheIgnoreNoLastMod On </Location> </VirtualHost> I have enabled the modules:
sudo a2enmod cache sudo a2enmod cache_disk sudo a2enmod expires sudo a2enmod headers And restarted apache without any errors. After clearing my browsers cache and browsing my site I expect content to apear under
/var/cache/apache2/mod_cache_disk/ But this is what I see all the time:
root@server:~# ls -la /var/cache/apache2/mod_cache_disk/ total 8 drwxr-xr-x 2 www-data www-data 4096 Apr 18 11:29 . drwxr-xr-x 3 root root 4096 Jun 29 08:07 .. I don't seem to be caching anything?!
When I add logging I get a bunch of minus signs "-" using LogFormat "%{cache-status}e ". The minus signs increase in number, but what does it mean?
Log files:
root@server:~# ls -l /etc/apache2/logs/ total 4 -rw-r--r-- 1 root root 1059 Aug 26 04:47 cache.log -rw-r--r-- 1 root root 0 Aug 26 03:53 cached-requests.log -rw-r--r-- 1 root root 0 Aug 26 03:53 invalidated-requests.log -rw-r--r-- 1 root root 0 Aug 26 03:53 revalidated-requests.log -rw-r--r-- 1 root root 0 Aug 26 03:53 uncached-requests.log
