disable pool member with an irule

I try to disable pool members with an http-request. The request has the form :

 

 

http://VIRTUAL_SERVER/down/NODE_IP

 

 

I wrote this irule:

 

 

when HTTP_REQUEST {

 

if {[scan [HTTP::uri] "/down/%s" server] == 1} {

 

LB::down node $server

 

log local0. "URI: [HTTP::uri] MATCHED. server=$server"

 

} else {

 

 

}

 

}

 

 

The irule seems to work, because if i call the URL, i get an log entry:

 

Oct 26 15:00:37 tmm tmm[1955]: Rule MN_NODE : URI: /down/192.168.0.11 MATCHED. server=192.168.0.11

 

 

But the server won't be disabled. What did i wrong?

 

 

thanks for help...

    it is a bug i.e. Bug 222047 - LB::down node does not work (Formerly CR 110633) LB::down and LB::down pool ... work fine. 

    [root@iris:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.17.33:http
   ip protocol tcp
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@iris:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
   if {[scan [HTTP::uri] "/down/%s" server] == 1} {
      LB::down pool foo member $server 80
      log local0. "URI: [HTTP::uri] MATCHED. server=$server"
  }
}
}

[root@iris:Active] config  curl -I http://172.28.17.33/down/10.10.70.110
curl: (52) Empty reply from server

[root@iris:Active] config  cat /var/log/ltm
