Testing arbitrary HTTP headers

I recently had an issue with Google Web Accelerator breaking one of my
AJAX apps and stumbled across this web page:


This seems a good idea for web applications, but I'm wondering how I can
achieve something equivalent to 

if ($x_moz = prefetch) {
    return 404;

since $x_moz isn't a predefined Nginx variable.  It also raises the
larger question of how to test against arbitrary HTTP headers.
