使用javascript模拟referer iframe?

my question is this

I have 2 sites, SiteA, SiteB, and what I want is to pretend that the traffic of a website through an open iframe in SiteA, simulate SiteB come from, for example we have:

*SitioA.com/index.php

*SitioB.com/redirect.php (Placed a javascript that redirects to the site I want it to open in the iframe, so the javascript code clears the referrer)

In SitioA.com/index.php, I put an iframe to call SitioB.com/redirect.php, which, in turn redirects with javascript to the web that I want to simulate the referer, here I leave the code to understand better:

In SitioA.com/Index.php I put:

<iframe class="premium_frame" src="http://SitioB.com/redirect.php" width="1000" height="1000" scrolling="no" frameborder="0"></iframe>

In sitioB.com/redirect.php, I put:

window.location.href = "http://jaqhegrjghegr.com";

Doing this is no way to jaqhegrjghegr.com for example, discover that the check actually comes from SiteA and not SiteB? that's my question
