If AllowOverride is enabled throughout the entire site, the server digs through every directory, searching for .htaccess files. To prevent this, simply disable the AllowOverride in the site's root .htaccess file.
To increase performance on PHP servers, simply add the following line to your .htaccess:
<ifmodule mod_php5.c> php_value zlib.output_compression 16386 </ifmodule>

If you have an admin section in your website and you only want specific users to access it (other than username and password). You can use the IP address to deny or allow unauthorized user to access it. Simply add the following lines to your .htaccess
order deny,allow deny from all # allow some ips allow from 192.168.1.0/24 # block one unique IP addresses deny from 192.168.1.101 # allow one unique IP addresses allow from 192.168.1.102 # block one ranges of IP addresses deny from 192.168 deny from 192.168.1 # allow one ranges of IP addresses allow from 192.168 allow from 192.168.1
Note: obviously the IPs will changed based on your network configuration or host ip.

ErrorDocument 404 /error_404.php ErrorDocument 500 /error_500.php #... and all other page code errors
