http_referer in a SSI directive

In a static page used by the error_page directive:
error_page 500 /static/xhtml/500.html;

I want to add a link "back" using the referer header.

Using SSI the solution can be something like:
<a href="<!--#echo var="http_referer" -->">Go Back</a>

However this does not works on nginx (0.5.18), and I got
<a href="(none)">Go Back</a>

This is a strange limitation, is the code correct?

Thanks  Manlio Perillo
