I know the message needs to be before any other text, but I'm having trouble with this.<br class="">Background: I have a script that is indexed by all the search engines. It has a parameter which is a item number (e.g. <a href="http://example.com/cgi-bin/script.pl?nnnnnn" class="">http://example.com/cgi-bin/script.pl?nnnnnn</a> ) where nnnnnn is a item number. The script figures out if this is a current item number and forwards it to an HTML page if it is. If it isn't a current item number, I create a page that is a similar product. The item numbers (nnnnnn) are added and deleted all the time. I want the search engines to stop indexing expired items, so I want to create a 404 error but still produce a page for the end user.<br class=""><br class="">I thought there was a simple print statement I needed to write out, but I'm having trouble figuring out what it is.<br class="">Thanks in advance.<br class="">Jim<br class=""><br class="">_______________________________________________<br class="">Chicago-talk mailing list<br class=""><a href="mailto:Chicago-talk@pm.org" class="">Chicago-talk@pm.org</a><br class="">http://mail.pm.org/mailman/listinfo/chicago-talk<br class=""></div></div></blockquote></div><br class=""></div></body></html>
