Forward using hostname as node, not IP

Hi,

 

 

Thanks for the advice so far, but something is not working right. My iRule as it stands reads like this:

 

 

when RULE_INIT {

 

set ::hostname "example.com"

 

set ::max 10

 

set ::count 0

 

set ::server_ip "192.168.0.1"

 

}

 

 

when CLIENT_ACCEPTED {

 

node $::server_ip 80

 

incr ::count

 

if { $::count == $::max } {

 

set ::count 0

 

NAME::lookup $::hostname

 

}

 

}

 

 

when NAME_RESOLVED {

 

log local0. "NAME_RESOLVED: [NAME::response]"

 

set ::server_ip [NAME::response]

 

}

 

 

It works fine to start with, and after the max limit is reached the lookup fires off. I then get the NAME_RESOLVED event, yet NAME::response returns nothing, and the whole thing chokes. i can dig the destination hostname on the box no problem, so would assume that there is no inherent problem on the box in terms of dns resources. Additionally i would assume that that event would only be triggered on a valid resolution, not every single return value. Any clues guys?

 

 

Thanks
