Nginx outbound HTTP_REFERER not working

[jmadtech]

Nevermind, I figured it out.  Our site is HTTPS and the link that the
customer gave us is HTTP... according to
http://en.wikipedia.org/wiki/HTTP_referrer, "If a website is accessed
from a HTTP Secure connection and a link points to a non-secure
connection, then the referrer header is not sent".

Thanks so much for pointing me in the right direction!
