There is default CACHE path pointing to non existing folder (/opt/rh/jbcs-httpd24/root/var/cache/mod_proxy)

cache_path=${CACHE_ROOT-/opt/rh/jbcs-httpd24/root/var/cache/mod_proxy}

There will be problem with proper starting of jbcs-httpd24 server in case of missing file /opt/rh/jbcs-httpd24/root/etc/sysconfig/htcacheclean, which contains definition CHACHE_ROOT pointing to proper cache folder(CACHE_ROOT=/opt/rh/jbcs-httpd24/root/var/cache/httpd/proxy).

Suggestion: set default cache_path to already created /opt/rh/jbcs-httpd24/root/var/cache/httpd/proxy to avoid server startup failures.
