Adding backend server name as request header

[Dennis Jacobfeuerborn]

Hi,
I'm wondering if there is a way to add the name of the server chosen for
the request as a request header i.e. if the following server is chosen
for the request:

server back1 10.1.0.10:8080 check inter 20000

then I'd like to receive this header on the 10.1.0.10 system:

X-CustomHeader: back1

Is this possible?

Regards,
  Dennis
