The main purpose in writing this article is to share how to protect media files. That is because I discovered that someone will copy my entire article and then paste it into their own Blog. In fact, we can not prevent it to happen. So I have to use the rewrite module of apache server to stop it. If you are using your machine as a web server, please follow my below steps to enable rewrite module...

• 1. Confirm rewrite module has been enabled in your httpd.conf file.

# cat /usr/local/etc/apache22/httpd.conf | grep rewrite

LoadModule rewrite_module libexec/apache22/mod_rewrite.so

• 2. If you have enabled virtual host function, please modify this file httpd-vhosts.conf and then add the following contents of the blue tag：

# vi /usr/local/etc/apache22/extra/httpd-vhosts.conf

<VirtualHost *:80>
ServerAdmin bryan.yu@msa.hinet.net
DocumentRoot /usr/local/www/apache22/data/ardoros
<Location />
      RewriteEngine on
      RewriteBase /
      RewriteCond %{HTTP_REFERER} !^$
      RewriteCond %{HTTP_REFERER} !^http://www.ardoros.com(.*) [NC]--->Allow this site to access media files
      RewriteRule \.(jpg|jpeg|gif|css|swf|png|bmp|rar|zip|exe)$ - [F] --->Limiting these attached file names
</Location>
ServerName www.ardoros.com
ErrorLog /var/log/dummy-www.ardoros.com-error_log
CustomLog /var/log/dummy-www.ardoros.com-access_log common
</VirtualHost>

• 3. If you don't enable virtual host function, please modify this file httpd.conf in /usr/local/etc/apache22/ directory

# vi /usr/local/etc/apache22/httpd.conf

<ifmodule mod_rewrite.c>
      RewriteEngine on
      RewriteCond %{HTTP_REFERER} !^$
      RewriteCond %{HTTP_REFERER} !^http://www.ardoros.com(.*) [NC]
      RewriteRule \.(jpg|jpeg|gif|css|swf|png|bmp|rar|zip|exe|mp3)$ - [F]
</ifmodule>

• 4. When you have completed the above steps, please modify Wordpress related file .htaccess that can be found in your website root directory. Adding the following contents of the red tag

# vi /usr/local/www/apache22/data/your_web_directory/.htaccess

# BEGIN WordPress
#

<ifmodule mod_rewrite.c>
      RewriteEngine on
      RewriteCond %{HTTP_REFERER} !^$
      RewriteCond %{HTTP_REFERER} !^http://www.ardoros.com(.*) [NC]
      RewriteRule \.(jpg|jpeg|gif|css|swf|png|bmp|rar|zip|exe|mp3)$ - [F]
</ifmodule>

# END WordPress
