rewrite iRule for legacy domain

Hi. I am trying to fix a problem with a legacy application that is getting a new domain.

 

The app server is old and only handles absolute URLs, but is getting a new domain. I need to write an iRule that will handle clientside traffic with the new domain, but send all traffic to the server with the legacy domain name.

 

Can you please help?

    To clarify, I need the client-to-external-vip to be

     

    new.domain.com > VIP

     

    F5-to-servers > old.domain.com HTTPS headers

    Not sure if this works! But give it a try..

     

    when HTTP_REQUEST {

     

    HTTP::header replace Host "old.domain.com"

     

    }

     

    Apply this iRule to your new.domain.com VIP.

    You don't need an irule to do this, you can use a policy to re-write the host headers
