Visitors must come from...

[banpro]

Hi all,

I'm trying to write a small script that will ensure that my page only loads if visitors come to it from another specific page, otherwise it should redirect them to that first page. Here is what I have but it doesn't seem to work properly. Any ides or suggestions are appreciated and welcomed.

 
<?php
if($_SERVER['HTTP_REFER'] != "http://somedomain.com/comm3/redir.html")
 { 
 header("Location: [url]http://somedomain.com/comm3/index.php[/url]");
 }
?>

Thanks in advance,
Scott

I'd like to ask,
does the condition always seems to be true or false?
i.e any visitor even he cames from a link on the desired page is redirected too?

$SERVER['HTTP_REFERER'] not $SERVER['HTTP_REFER']

The following is which written about this in the manual
'HTTP_REFERER'
The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted.

The user agent here means the web browser.

you can use sesions to set a true value if the user have been on an other page!
