sending url name to server through f5 ltm

I need to load balance a RSA server that recognizes only hostname instead of the IP. When we access the vip which is configured on ssl, the bigip should open server side connection with the URL name and not IP, does this need an irule or can this be configured without irule?

  • Can I assume you're talking about a web-based interaction with your RSA server (HTTP)? If so, then there are a few considerations:

    1. In the absence of any other manipulation, the Host header created by the client browser will be sent untouched to the back end web server.

    2. If you need a different Host header, you can generally apply a simple iRule to change that value in transit:

      when HTTP_REQUEST {
          HTTP::header replace Host "my_rsa_server_1.domain.com"
      }
      

      which of course requires that you terminate the client side SSL at the proxy with a client SSL profile.
