In PHP I see that

$_SERVER['HTTP_REFERER']

gives me the refering url if the refering page had a link that was clicked through to my current page. But what if page A has a htaccess redirect that sends the user to page B. If I have the above snippet on Page B will I get Page A as the referer?

Or does it only work if a user clicks on a link that takes them to page B?

    To begin with: http://php.net/manual/en/reserved.variables.server.php

    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.

    To answer your question:

    Page A will be sent if it is silent rewrite (temporary redirect).

    Page B will be sent if it is a redirect that sends a 301 (permanent redirect).
