.htaccess: stop anti-leech from one referrer only

Hi,

I'm trying to redirect a leeching website to an anti-leech image, but
no luck. What am I doing wrong?

RewriteEngine on
RewriteCond %{HTTP_REFERER} ^http://www.somedomain.com/ [NC]
RewriteRule \.jpg$ http://www.mydomain.com/anti-leech.jpg [R,L]

It does stop the original image from being loaded, but in my access
log I see that it keeps trying to load the anti-leech image, but it
keeps serving a 302. It's like an infinite loop for some reason, but
why?

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http://(www\.)?somedomain\.com(/)?.*$ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteRule .*\.(jpg|jar|jm|php)$ http://www.mydomain.com/anti-leech.jpg
[R,NC]

Works for me - some of these are host dependent (what they have set that
I cannot touch) - I do not understand (yet) what I am doing - basically
cut and paste at this point or throw enough at the wall 'till something
sticks ;-).

Only if you want the anti-leech image to be visible in all cases
except when the referer is somedomain.com. The '!' stands for 'not'.
I wanted the opposite: only block one referrer.

Done that for a 'while' before I posted the message...

That's what I've been doing all evening (GMT+1), and this is what
stuck:

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_REFERER} ^http://www.somedomain.com [NC]
RewriteRule ^(.*)\.jpg anti-leech.jpg [L]

I guess the R (before the L) was keeping it in a loop. Not sure
though. At least it's working now, so I'm happy :-)

Sorry, you are right (as usual!).
I am trying to get anyone using my stuff to give me credit (come in
through the front door) - I do not care if they "steal" my images - they
are so *mine* that they will not do them any real good - they are also
small enough that they are not going to bleed serious bandwidth. The one
thing I am really trying to block is jar file usage and it does not work
on that.

Hi, Good lookin' :)

For me this more of a fun puzzle than serious problem.

Well, with that I can help.
Found this link:
http://www.bylandwaterandair.com/ext...ttribution.php
Works perfectly for me - any of my images that are leeched (and
visited by people who don't block the referrer) are now showing my URL
:-)

What is 'jar file usage' ?

I have no idea really, but apparently not - it's working already :-)

Same here, but I was quite determined to piss some people off who have
a membership at MySpace - they leech 800x600 and 1024x768 images as
background for their personal pages. It's not causing me to pay more
for my bandwidth, but still - just like to teach them a lesson I
think.

So those get my anti-leech image now, and all the others my URL
slapped on the image :-)

If it works - don't fix it!

The R means redirect, so you are sending the new URL back to the
browser and telling it to use it instead. When it hit your original
rewrite rules, it would get rewritten to itself - infinite loop.

HTH,

Thanks, I'll remember that :-)
