[users@httpd] Balancer Hot Spare

I'm using 2.2.2 trying to set up a hot spare as described here:
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypass

here is my config:

<Proxy balancer://vsBalancer>
BalancerMember http://192.168.200.190 loadfactor=1
BalancerMember http://192.168.200.206 status=+H
</Proxy>


I get the following error: "BalancerMember Unknow status parameter option"

When I try status=H I get the same thing? Am I missing something to do hot
spares? Do they not work in 2.2.2?
