I have APC set up and installed in Magento. I was wondering if there is a way I can confirm it is caching and working correctly. The pages seem to be loading fine, but I need to verify.
if you have dedicated server or vps, then you better upgrade php to the latest version and use ZendOpcache, it can be installed as a package or compiled in with
APC cache was discontinued, and available now as APCu
this is how to get all modules and php information: http://php.net/manual/en/function.phpinfo.php
or from shell:
php -m | grep apc
