I have been working on optimizing my APC settings. It has been going well for the most part, with one exception. I am trying it exclude a directory from the APC cache, and am trying to use the apc.filters setting to do it. I have read the documentation on the setting, and also scoured the internet for working examples. But to no avail, I cannot make it work - no matter what I try, it is still including my directory in the cache. The syntax for apc.filters is supposed to be regular expressions - and I struggle to understand them beyond simple usage. So my directory is located on this path in the server: /home/my_user/public_html/my_directory I have tried about a dozen combinations including: apc.filters = /my_directory/ apc.filters = /home/my_user/public_html/my_directory apc.filters = /my_directory/.* and more.... Can anyone out there help me with the correct syntax? (P.S. - I did put in a ticket with KH support on this, and they pretty much looked to me for the solution and didn't offer anything). Thanks!
