DNS Caches and iRules

Hi

Apart from a bracket issue on you if line - should be { rather than [

if { $dns_pool eq "pool_dns_NXDOMAIN" } {

which i'm guessing is a copy and paste issue as the code wouldn't work otherwise then your code works for me. When querying the VIP I can see requests for all of me DNS suffixes hitting the DNS servers but the call for the specific host in the Data Group gets served by the iRule.

Changing your code tocontains dg_dns_steering tidied this up for me.
