Export values for CL_HTTP_CLIENT= CREATE

Question

Hi All,
I am trying to use methos create of Class CL_HTTP_CLIENT
CALL METHOD CL_HTTP_CLIENT=>CREATE
   EXPORTING
     HOST               = host  "e.g. www.google.co.uk
     SERVICE            = port
     PROXY_HOST         = proxy_host
     PROXY_SERVICE      = proxy_port
     SCHEME             = scheme
  IMPORTING
     CLIENT             = client
   EXCEPTIONS
     ARGUMENT_NOT_FOUND = 1
     PLUGIN_NOT_ACTIVE  = 2
     INTERNAL_ERROR     = 3
     others             = 4.
My concern is how do we get 'PORT' value.
Also what value will go to proxy_host and proxy_port.
Is it value that is configured to internet connection for explorer ? How to get it?
Kindly site one example if possible. I have searched a lot on SDN bt m still not clear about the values and how to get them.
Regards,
Sangvir Singh
