blocking all sites and redirecting

[proxyHunter]

I know how to block all domains except my own from hotlinking

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http://mysite.com.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http:De//www.mysite.com.*$ [NC]
RewriteRule .*.(gif¦GIF¦jpg¦JPG)$ - [F]

but i also want to stop a few sites (some i don't know about) from doing this:

<img src="http://mysite.com/" width="1" height="1">

and adding to my bandwidth.

I do know how to stop domains with certain keywords:

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_REFERER} "cartoon" [OR]
RewriteCond %{HTTP_REFERER} "movies"
RewriteRule .* http://redirecthere.com [L]

but is there a way to stop all other sites and redirect them?

(this doesnt work)

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_REFERER} !^http://mysite.com.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.mysite.com.*$ [NC]
RewriteRule .* http://redirecthere.com [L]

proxyHunter,

You have to use an external redirect if you want to send them off to another site. Fixing that, as well as combining your two RewriteConds into one, gives:

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mysite.com.*$ [NC]
RewriteRule .* http://redirecthere.com [R=301,L]

However, it may be more efficient to simply 403 them and be done with it:

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mysite.com.*$ [NC]
RewriteRule .* - [F]

Or, if you have a custom 403 page:

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mysite.com.*$ [NC]
RewriteRule!^my_custom_403_page\.html$ - [F]

Note with all of the code variants above, you will block anyone whose referer is blank. This will include anyone who enters your URL directly, uses a bookmark, or who is behind a corporate proxy or internet security program which blocks referrers. I believe that blocking blank referers is a bad idea, and will give most webmasters major 'customer support' headaches. Therefore, despite the fact that it opens a 'hole' in the hot-link blocking, I suggest you allow blank referers, like so:

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mysite.com.*$ [NC]
RewriteRule!^my_custom_403_page\.html$ - [F]
