RemoveType in .htaccess

If you have multiple users' pages sitting under one directory you can make it more secure with
RemoveType directive, just place .htaccess in the top level directory. For example:

/www is the web server root
/www/users is the directory where user directories are
/www/users/dummy is the directory where user named dummy keeps his/her webpages

Create .htaccess in /www/users and put the following lines in it. I'm assuming you will not
allow users create files starting with . (dot)

RemoveType .cgi
RemoveType .php

Add / remove other types depending on what you are runnig on your server.
