Hi i'm trying to switch over from using apache form .htaccess for referer management and have run into some problems. My hosting co. don't want to help much and direct me here but i can't find the answer i am looking for.
Quite simply, I want to stop hotlinking to images that reside in my website.
I have tried the following rewrite.script and saved it at the folder that has the images i want to protect:
match URL into $ with \.(gif|jpg|jpeg)$
if matched
match IN:REFERER into $ with ^(www\.)?.+\.bryan-talbot\.com$
if not matched
set URL = http://www.test.com/donotsteal.jpg
endif
endif
As you can see - what i want to acheive is that when a visitor comes and hotlinks an image the is on my site, i want to present my do not steal image instead.
It does not seem to work.
I have searched high and low on the net and found very little on how to do this.
Any good ideas?
Many thanks.

Hi Rob,
Rewrite scripts must be installed into the Web Server, rather than residing in directories as Apache .htaccess files do - so unfortunately you are going to require the assistance of your hosting company to get this to work. The two best options that you have are either to continue using .htaccess files to perform your filtering (since ZWS does support Apache-style .htaccess files - but your host will need to have enabled this) or you could ask your host to implement a rewrite rule which " execute"s an arbitrary file inside your document root which contains further rules written by you.Hope this helps!
