Prevent Hotlinking and Bandwidth Theft

Author: Stoker
Description: Here is a little addon for Your phpBB3 board that prevents hotlinking.
It only affects files that are uploaded with the "Upload attachment" function.
Uploaded Avatars, files and images are included.
This way it only causes very little server load because it only checks files placed in the download folder.
Note! Only works on servers running Apache!

Attached file:

prevent hotlinking.zip

Demo: Copy and post this links at Your own site:

Code: Select all

http://www.phpbb3bbcodes.com/download/file.php?id=213
http://www.phpbb3bbcodes.com/download/file.php?id=162&mode=view/stats.png

Intructions:
Download the zip file, unzip it and open root/download/.htaccess file
It looks like this:

Code: Select all

RewriteEngine On
RewriteCond %{HTTP_REFERER} !^http://(.+.)?yourdomain.com/ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteRule .*.(php)$ ../stop.gif [L]

Change yourdomain.com to Your domain name.
Example:

Code: Select all

RewriteEngine On
RewriteCond %{HTTP_REFERER} !^http://(.+.)?phpbb3bbcodes.com/ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteRule .*.(php)$ ../stop.gif [L]

Upload root/download/.htaccess to root/download
Upload root/stop.gif to root
Offcourse You can use any other pic at Your own choice.

FAQ:
Q - What if I want to allow more domains to hotlink?
A - It is easily done. Lets say that phpbb.com should be allowed to hotlink, just use this:

Code: Select all

RewriteEngine On
RewriteCond %{HTTP_REFERER} !^http://(.+.)?phpbb3bbcodes.com/ [NC]
RewriteCond %{HTTP_REFERER} !^http://(.+.)?phpbb.com/ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteRule .*.(php)$ ../stop.gif [L]

You can add several domains if needed. Just add an extra line as the example above.

You save bandwidth i could come to your site and get the links of an image or a file and place it on my site but you pay for the bandwidth and i get it free as you have paid for it.

Place these on your site in a forum post and click them

Code: Select all
