<?php
$test = join('', file('http://your.server.com/more123.html'));
if(eregi('not found', $test)){ //Test against a string in your 404 page
echo 'No details currently available.';
}
else{
echo "<a href='/more123.html'>More Details</a>";
}
?>
Just edit the URL that $test is looking up based upon wherever the
details link would point for that particular record. Make sure the eregi
() call is testing against a string that appears in your ErrorDocument
404.
