Jump has been designed to prevent other sites logging your content sensitive pages as a refering url.
WHY ? so that they will never be able to find your web page that may have information on it you don't want others viewing.
Simply change your links to point to jump.cgi then add the real url you are linking to
after the ?url= part. ie:
http://yourdomain.com/cgi-bin/jump.cgi?url=http://something.com/page.htm
