@felgallMay 31.2006 — You also can't rely on referrers as that field is under your visitor's control. If they don't want you to know where they came from then this field will be blank or contain a dummy value (depending on which browser or firewall they used to disable it).

I've seen nothing that would support that statement. Instead, everything I've seen, and experienced for myself, says that the HTTP REFERRER header is under the control of each web server. However, the end result is the same -- the HTTP REFERRER header may or may not be present.

The referer can easily be spoofed. Take this test page I setup for example:

<i>
</i>&lt;?php
$r=$_SERVER['HTTP_REFERER'];
if($r != "https://www.ultimater.com/admincp.php"){
?&gt;
Only members from our trusted site &lt;a href="https://www.ultimater.com/admincp.php"&gt;https://www.ultimater.com/admincp.php&lt;/a&gt; can view this page's content.&lt;br&gt;
&lt;?
}else{
?&gt;
Congratulations! you have successfully spoofed the referer!
&lt;?
}
?&gt;

First enter it directly:

http://aplustv.com/public_stuff/httpreferer.php

Now try spoofing it with PHP:

http://aplustv.com/public_stuff/spoofer.php?url=http%3A%2F%2Faplustv.com%2Fpublic_stuff%2Fhttpreferer.php&referer=+https%3A%2F%2Fwww.ultimater.com%2Fadmincp.php

Yeah, I've seen your spoof. But it doesn't address the issue posed. Then again, perhaps you just wanted to make the OP aware of it, too. :p

Are you suggesting you would rely on referrers even if it can be spoofed?
Copy linkTweet thisAlerts:
@phpnoviceJun 01.2006 — "rely" is an indefinite word. ? But that wasn't my point. My point was only about the normal source of a referrer. It is server defined, controlled, and transmitted. It is not visitor-controlled -- as was suggested. Sure, can be visitor-spoofed, but that is an abnormal source.

Success!
