DATA: cl_request  TYPE REF TO IF_HTTP_REQUEST,
        lt_header_fields TYPE tihttpnvp,
        ls_header_fields LIKE LINE OF lt_header_fields.

  cl_request = wdr_task=>request.
  DATA: name TYPE string,
        value TYPE string,
        data TYPE xstring.
  CALL METHOD cl_request->if_http_entity~get_header_fields
    CHANGING
      fields = lt_header_fields.

Direct access to the wdr_task object is not supported by SAP. SAP can make incompatible changes to this object at any time.

This should give you access to application specific headers. There are APIs for reading some of the system level headers. For instance in IF_WD_APPLICATION, you can get the Remote IP address and the Client Environment. These methods are just wrappers around WDR_TASK, but they ensure safe and permanent access to it.

This is important functionality cut by the ABAP Web Dynpro Runtime. The above links don't help.
