I am trying to prevent hotlinking of my images and using the following
script on my SUSE 11 server

RewriteEngine On
RewriteCond %{HTTP_REFERER} !^http://(.+\.)?mysite\.com/ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteRule .*\.(jpe?g|gif|bmp|png)$ http://mysite.com/hotlink.gif [L]

It isn't working correctly for some reason - can anyone tell me why?

When you have sufficient supplies and ammo, the emeny takes 2 weeks to
attack. When you are low on supplies and ammo, the enemy decides to
attack that night.

There is no problem that cannot be solved by the use of large

You don't have a R here which you may require since you're specifying a
link to an external site, even if it's really the same site.

Now, what's the actual error? Are you getting a "500 server error"? If
so, probably haven't allowed rewriting in the server configuration
and/or enabled mod_rewrite.

As an example, I've added a .htaccess to my site for testing. The
contents is:

davjam(a)moray:~/public_html/test> cat .htaccess
RewriteEngine on

# test to see if images are pinched from elsewhere
#
RewriteCond %{HTTP_REFERER} !^http://(www\.)?davjam.org$ [nc]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?davjam.org/.*$ [nc]
RewriteRule .*\.(jpe?g|gif|bmp|png)$ http://www.google.com/ [nc,r,l]

davjam(a)moray:~/public_html/test>

And a quick test of it returns the expected redirect to Google:

davjam(a)moray:~/public_html/test> curl -x '' -A '' -v http://www.davjam.org/~davjam/test/test.jpg
