Regarding HTTP error code 'NA'

Hi guys.

I`m doing POC using v12.1.3.6 BIGIP 7000 and provisioning LTM + AVR.

purpose of POC is well-doing, but there is not clear thing.

I`m using tcp profile + HTTP profile + HTTP avr profile + i-rule

i-rule is logging HTTP RESPONSE code start 4 or 5, log client IP port and LB server IP port and requested URI URL.

when HTTP_REQUEST { set http_host [HTTP::host] set http_url [HTTP::uri] } when HTTP_RESPONSE { if {([HTTP::status] starts_with "4") || ([HTTP::status] starts_with "5")} { log local0. "Status Code : [HTTP::status] URI : $http_host$http_url Client = [IP::client_addr]:[TCP::client_port], Server = [IP::server_addr]:[TCP::server_port]" } }

but In AVR, there is weird thing.
