HTTPS source connections should not require a port setting

Current Situation

• HTTPS source connections require a port setting such as:

  protocol = http
  auth_method = url
  host = https://uk.sos-berlin.com
  port=443

Desired Behavior

• No port setting should be required
  • Port 443 is the default port for HTTPS as stated in the docs. (The problem might be due to the fact that effectively the http protocol is specified for such connections and https is specified with the URL).
• Should different ports have to be used then they should be specified by the URL and not by a port setting

Testcase

• see proxy.ini, profile copy_from_uk_https_via_proxy
