Replace server hostname with DNS name

I'm sorry if I was unclear - I'm very new to LTMs and this forum. I a DNS name; in this case http://ora-dev1. Which gets directed to a pool that has 2 member servers.

 

Once at the login page we start to see the name of the server: http://servername.mycompany.com:8016/OA_HTML/AppsLocalLogin.jsp?requestUrl=APPSHOMEPAGE&cancelUrl=http%3A%2F%2Fservername.mycompany.com%3A8016%2Foa_servlets%2Foracle.apps.fnd.sso.AppsLogin

 

 

I would like to replace servername.mycompany.com with http://ora-dev1

 

 

I'm not sure how to accomplish this with an irule.
