php hitbot detection

[matt]

A couple of things i noticed at a glance...

Maybe this:

<? echo $_SERVER['HTTP_REFERER']; ?>

Should be

<? echo urlencode($_SERVER['HTTP_REFERER']); ?>


Or possibly this:

mail("proxy@domain.com", "Hitbot:", "From: $from\r\n");

should be

mail("proxy@domain.com", "Hitbot:", "From: " . $_GET['from'] . "\r\n");


How do you know the variable is being passed to the go.php file?
