I am hosting a several sites on IIS 6 and was wondering if it is possible to
block access to visitors by referrals. One of the site I have is a shareware
site and there is a hotlink from a warez site which I want to block off. The
trouble is that I do not know who visits those sites and cannot block by IP.

Thanks.

Edwin

there are commercial ISAPI filters that can do this.

or you could write your own.

Hello,

IsapiRewrite can do this:
http://www.isapirewrite.com/

There are also open-source code available:
http://www.michaelbrumm.com/leechblocker.html

Just a note:
The referrer is sent by the client, so it is possible that the client does
not send the referrer, or sends a false one. But an ISAPI filter will
catch most of the clients, but probably not all, because the referrer
field will be false.

Hope this helps you solve your problem!

Good Luck!

Thanks. I did try IsapiRewrite but installing got my own server
unreachable. I guess I will read it further to see how to get it
to work.
