> http://...:gopher

is it http or gopher? :)

i chose gopher port just as an example. try with any other service name mapped to a port number from /etc/services and the result will be the same. the OP's goal was to use many http/https services, so we are talking about many http(s) services.

i just wanted to make the point that even if you have service names in /etc/services, it is not possible to use that names easily to host/access http(s) services.
