To properly make use of this script, you must hyperlink to it from a Web
document with an external URL in the QUERY_STRING
, so that
this script knows where to redirect the user to.
For example, the following is a properly structured hyperlink:
<A HREF="/cgi-bin/intercept?http://www.doi.gov/"> Go to the DOI Web Server </A>As a result, this script will dynamically output HTML warning the user of the external material, and offer a direct hyperlink to the server.
