Apache CacheMaxExpire directive ignored

Issue

• Currently setting up mod_cache together with mod_cache_disk to cache content from reverse proxy. CacheDefaultExpire seems to be ignored when configured with the Location directive.
  However when we setup CacheDefaultExpire in the Location section instead of CacheMaxExpire it starts expiring as required, but this should be done by CacheMaxExpire.
• The CacheMaxExpire setting from the http config is ignored when you use the cache module. The age in the response header exceeds the setting we specified with the CacheMaxExpire directive. Only when the Expires header time is reached doesthe content expires
