Disable sun one webserver from displaying server information within response header

Start Web Server 7 Administration Server
Run the below command line
wadm set-http-prop --user=admin --config= server-header=""
wadm deploy-config --user=admin

which does nothing but adding the ServerString none value in magnus.conf file,
you may also change it to ServerString apache where apache is your custom or misleading info.
below is an example.
