NAME_RESOLVED not firing

Dear Forum,   I'm trying to get DNS resolution working from within an iRule in v9.4.6.   I've based the rule on the example in https://devcentral.f5.com/Default.aspx?tabid=53&forumid=5&post...

Hi Matt,

 

 

Unfortunately node command seems to be simply ignored in NAME_RESOLVED. I mean variables are set properly and my messages logged but node does not work. I can see with tcpdump that whenever node command is in HTTP_REQUEST (dummy 'node 10.10.10.10 80' in fact) then I see SYN packets sent out. But when I move node command to NAME_RESOLVED tcpdump shows literally nothing. Just NAME_RESOLVED below.

 

 

when NAME_RESOLVED {

 

set real_server [lindex [split [NAME::response] " "] 0]

 

log local0. "in name-resolved"

 

if {$::debug}{log local0. "XXX $real_server XXX in NAME RESOLVED"}

 

HTTP::release

 

node $real_server 80

 

node 10.10.10.10 80

 

if {$::debug}{log local0. "UUU $real_server UUU in NAME RESOLVED"}

 

}

 

 

 

Regards

 

 

Andrzej
