I'm trying to setup carp + hoststated as a loadbalancing solution on
the loadbalancer I have hoststated with 2 service one and 2 ips on the
carp interfaces
1 for dynamic and one for static content the dynamic content works
fine but when I try to use both of em the traffic seems to end up on
the wrong backend
hoststated config

ext_addr="xxx.xxx.xxx.242"
static_addr="xxx.xxx.xxx.243"
webhost2="192.168.1.142"
static1="192.168.1.32"
table webhosts {
real port http
check http "/" code 200
timeout 1000
host $webhost2
}
table staticserver {
real port http
check http "/unavailable.html" code 200
timeout 1000
host $static1
}
table fallback {
real port http
check icmp
host 127.0.0.1
}
service www {
virtual host $ext_addr port http
tag HOSTSTATED
table webhosts
backup table fallback
}
service static {
virtual host $static_addr port http

table staticserver
