how gmail hide http referrer?

[nokiamobile]

Hi,
anyone know how gmail hide http referrer when a link in email is
clicked?


If you would like to try:
send to your gmail address in body text, this URL:

http://wwwhomes.uni-bielefeld.de/cgi-bin/cgiwrap/achim/server.html

Open your gmail account and try to click it.

will you find HTTP_REFERER field empty.

How is it possible?

Is it possible in php?
Thanks!
