Matching packets by HTTP header "Host"

Hi all.
I'm trying to forward packets to different hosts depending on the "Host"
header in HTTP packets, e.g. packets on port 80 requesting "Host:
one.example.org" to 192.168.0.1 and all other on port 80 to 192.128.0.2.
I did:

iptables -t nat -A PREROUTING -p TCP -i eth0 -m string --algo bm
- --string "Host: one.example.org" --destination-port 80 -j DNAT
- --to-destination 192.168.0.1

iptables -t nat -A PREROUTING -p TCP -i eth0 --destination-port 80 -j
DNAT --to-destination 192.168.0.2

But all packets are going to 192.168.0.2. Do I miss something?

Regards,
G.L.
