Since I installed PHP 4.3.10 and 5.0.3 the HTTP_REFERER produces the following error "Notice: Undefined variable: HTTP_REFERER in c:\inetpub\wwwroot\PHP\PHP_2party.php on line 444"

The same code has worked successfully in previous versions of PHP.

Is this something that should work still or has it been deprecated?

Reproduce code:
$againLink  = $HTTP_REFERER;
<p><a href='<?=$againLink?>'>Another Transaction</a></p>

Expected result:
The code should create a hyperlink back to the previous page. It is done in this manner as different HTML pages call this one transaction page.

Actual result:
The error indicated above is written to the screen and the hyperlink is not complete. For example the incomplete hyperlink is shown as: http://localhost/PHP/ instead of: http://localhost/PHP/PHP_2party_Order.html This means the browser does not return to the original location when the hperlink is clicked.

In PHP 4.2.0, the 'register_globals' setting default changed to
'off'. See for more info.
We are sorry about the inconvenience, but this change was a necessary
part of our efforts to make PHP scripting more secure and portable.
