404 Error Referer Script Problems

[Alex]

Hello,

I am having trouble extracting the original referer in my 404 error script.
This is what I have so far:

1) I set the .htaccess file to the following and it works fine:

ErrorDocument 404 /404.php

2) I've tried the following variables and they all produce the same results:

$REQUEST_URI
$HTTP_REFERER
$REDIRECT_URL

3) The above mentioned variables all return "/404.php" and not the
originally requested page.

I'm a little new at this and any assistance would be greatly appreciates!

Many Thanks,

Alex

$REQUEST_URI returns the correct thing for me.

What you want is:



<?php
if (isSet ($_SERVER['HTTP_REFERER'])) {
# if (eregi (('http://' . $_SERVER['SERVER_NAME']), $_SERVER['HTTP_REFERER'])) {
echo "\n<p>A message to the webmaster has just been sent automatically, to inform her/him to make arrangements$

$recipient = 'webmaster@YOUR DOMAIN';
$website_name = 'NAME OF WEBSITE';

$subject = "{$_SERVER['SERVER_NAME']} error: 404 (non-existent resource)";
$mailheaders = "From:$websiteN ame website monitor <$recipient>\n" ;
$message = "\nA 404 message was generated from someone loading a resource on {$_SERVER['SERVER_NAME']}\n\n";
$message .= " The resource is at {$_SERVER['HTTP_REFERER']}\n";
$message .= " which attempts to load http://{$_SERVER['SERVER_NAME']}{$_SERVER['PHP_SELF']}";
$browserDescrip tion = (isSet ($_SERVER['HTTP_USER_AGEN T']) ? $_SERVER['HTTP_USER_AGEN T'] : '');
$message .= "\n\n" . $_SERVER['REMOTE_ADDR'] . "\n" . $browserDescrip tion;
mail ($recipient, $subject, wordwrap ($message), $mailheaders);
# }
}
?>




(Sorry if the lines wrap.)

Uncomment the two lines beginning with # if you want to enable broken link
detection for referrers ONLY within your site.

Bear in mind that you will get a few spurious results due to badly
configured spambots/scumbots and all sorts of other rubbish out there. If
you get a referrer of www.iaea.org I personally would ban that IP.
