You can use an iRule to inject a HTTP header with this info.
when SERVER_CONNECTED { set node [IP::remote_addr] } when HTTP_RESPONSE { HTTP::header insert {LB-SERVER} $node }# curl -v http://10.130.4.50 -o /dev/null ...[Omitted] HTTP/1.1 200 OK < Date: Tue, 18 Aug 2020 08:18:42 GMT < Server: Apache/2.2.15 (CentOS) < X-Powered-By: PHP/5.3.3 < Content-Length: 7677 < Connection: close < Content-Type: text/html; charset=UTF-8 < LB-SERVER: 172.16.1.2Regards,
