Add server-id to response header

[Jan-Oliver John]

Hi guys,

is it possible to set a response header that includes the server id the 
request has been sent to?

Maybe with "rspadd <something>"?

for example (conf):

---

frontend vs_something
    ....
    rspadd server-id     # either server1 or server2

backend pool_something
    balance roundrobin
    option ....
    server 1  server1    1.1.1.1:80
    server 2  server1    2.2.2.2:80

---

Thanks,
Oliver
