how can i get the url form history.go(-2)
<p>hi have a question, is it possible to get the url from the history.go(-2)?
Asuming i don't know that url.</p>

<p>thanks,
Sebastian</p>

<p><strong>edit</strong></p>

<p>i need the url, because i want to check where the visitor was redirected from. there are two cases: 1 facebook, 2 directly on the website. the second step is an automatic user check. the third step is misscoded, but if i go back to step 1. i can bypass the error. with everything working fine. the problem is that i don't know where to redirect (being two forwarders).</p>
