  • Small system footprint
  • Code readable in git repository

Connectivity

cl_http_client=>create_by_url(
  EXPORTING
    url    = 'https://github.com'
    ssl_id = 'ANONYM'
  IMPORTING
    client = li_client ).
li_client->request->set_cdata( '' ).
li_client->request->set_header_field(
  name  = '~request_method'
  value = 'GET' ).
li_client->request->set_header_field(
