WebLogic webapplications returning HTTP 302 Moved Temporarily

If I configure a HTTPFRONTEND HOST to the LoadBalancer lbr.acme.com (5.6.7.8), when I contact directly a Managed Server myserver.acme.com in the cluster, results in a HTTP redirect with the new location pointing to the LoadBalancer.
I am struggling to find out how to disable this.

wget http://myserver.acme.com:8001/gridlinkha

setting max-redirect=0 makes the request fail altogether:

wget --max-redirect 0 http://myserver.acme.com:8001/gridlinkha
