Hi Antonio,
Yes this is possible. Check out class cl_http_client, particularly method IF_HTTP_CLIENT~AUTHENTICATE in which you can provide the user credentials. Here's some example code:
DATA:  client    TYPE REF TO if_http_client,
             l_url       TYPE string,
             l_content TYPE string.
CALL METHOD cl_http_client=>create_by_url
  EXPORTING
    url    = l_url
  IMPORTING
    client = client
  EXCEPTIONS
    OTHERS = 1.
client->request->set_header_field( name  = '~request_method'
                                   value = 'GET' ).        "#EC *
CALL METHOD client->authenticate
  EXPORTING
*    proxy_authentication = ' '
*    client               =
    username             = 'user'
    password             = 'password'
*    language             =
****Make the call
client->send( ).
****Receive the Response Object
CALL METHOD client->receive
  EXCEPTIONS
    http_communication_failure = 1
    http_invalid_state         = 2
    http_processing_failed     = 3
    OTHERS                     = 4.
****Get the response content in Character format
l_content = client->response->get_cdata( ).
Hope this helps you!
