I'm updating my Apache module (available in code section) and I'm wondering if the $r->dir_config call checks the config file each time, or if it stores all of the key value pairs in a hash. Since one of my values (DefaultLimit) will be in the httpd.conf file, and one of them (TimeLimit) will be user supplied in an .htaccess file, should I just call them both (if they exist) and store in temp variables, or should I just call them using the $r->dir_config each time they are needed?

I know this is a mod_perl question and not specifically a perl question, but I still think it is worth looking into.

For instance: 

        if ($r->dir_config('TimeLimit')) {
                if ($r->dir_config('TimeLimit') < $r->dir_config('Defa
+ultLimit')) {
                        $time_to_die = $r->dir_config('TimeLimit');
                } else {
                        $time_to_die = $r->dir_config('DefaultLimit');
                }
        } else {
                $time_to_die = $r->dir_config('DefaultLimit');
        }

Or 

     my ($default, $time_to_die, $limit);
     $default = $r->dir_config('DefaultLimit');
     $limit = $r->dir_config('TimeLimit') if ($r->dir_config('TimeLimi
+t'));
     ($limit < $default) ? $time_to_die = $limit : $time_to_die = $def
+ault;

Any ideas?
