Description:

Trying to disable the caching of PHP files for a certain directory using the php_flag directive in .htaccess, and it's not having any effect.

The apc.cache_by_default option appears to be turned off in the directory, but the files still get cached.

Reproduce code:
---------------
.htaccess contents:

php_flag apc.cache_by_default 0
