Retrieve node fqdn or node name using an Irule

Hello Guys,

I want to retrieve using an irule the fqdn of the node.

As you know we can create a node using 2 ways: with IP or Fqdn.

In my way I create node only unsing FQDN and what I need is to retrieve FQDN value or Node name (I don't want IP add).

Second point I know that I can use Reverse dns an retrieve Arecord of my node but in my situation I can't because I have several Arecord on the same node.

Second point I know that I can use a DG with with a correspondence table which can be enriched with an ICALL or others but I wanted to see if there were some more simple things.

Last important information, I am migrating an apache configuration, and apache does it in a native way using the following command:

ProxyPreserveHost Off

This command allow to replace Client Host value by fqdn node...

Thank you for your help.

Regards,
