How can I open a new window for a (calculated) PDF?

Question

Hi,
I have a BSP application with MVC. The start page is a HTML/HTMLB page with some buttons. If you click on the buttons, you get a PDF document in the same browser window. I generated the PDF over smart forms from table/Cluster data.
I call the controller in the OnInputProcessing event handler of the page and give it the parameters.
The problem: if you are on the PDF you cannot come back to the start page. I think, it is better, if the PDF gets a new window. The user can open on this way many PDF docs.
I tryed with navigation->next_page(...) or call_view etc. but all this dosn't work. Only the PDF will be show and in the same window!
Do I have to separe the application in two applications and use the CALL_APPLICATION method?
Or does anyone know a better way?
Thank you!

HI Thomas,
I send you a fragment of the code. It does work well.
Thank you for the links!
The data are read, convert into a otf, then in pdf
CALL METHOD me->print_otf_2_pdf
      EXPORTING
        otfdata    = model->otf
        response   = response
        navigation = navigation.
METHOD print_otf_2_pdf .
generated result: PDF format
  DATA: l_pdf_xstring  TYPE xstring,
        linetab        TYPE tlinetab,
        l_pdf_len      TYPE i.
Conversion of output format OTF into PDF format
now convert the final document (OTF format) into PDF format
  CALL FUNCTION 'CONVERT_OTF'
       EXPORTING
         format                      = 'PDF'
       MAX_LINEWIDTH               = 132
       ARCHIVE_INDEX               = ' '
       COPYNUMBER                  = 0
       IMPORTING
         bin_filesize                = l_pdf_len
         bin_file                    = l_pdf_xstring       " binary file
       TABLES
         otf                         = otfdata
         lines                       = linetab
       EXCEPTIONS
         err_max_linewidth           = 1
         err_format                  = 2
         err_conv_not_possible       = 3
         err_bad_otf                 = 4
         OTHERS                      = 5
  IF sy-subrc <> 0.
  ENDIF.
  CALL METHOD me->open_pdf
    EXPORTING
      pdf_xstring = l_pdf_xstring
      pdf_len     = l_pdf_len.
ENDMETHOD.
METHOD open_pdf .
  DATA: l_pdf_len  TYPE i,
        runtime    type ref to if_bsp_runtime,
        filename   type string,
        guid       type guid_32.
  response->set_header_field( name  = 'content-type'
                            value = 'application/pdf' ).
  response->set_header_field(
                    name  = 'cache-control'
                    value = 'max-age=0' ).
   l_pdf_len = XSTRLEN( pdf_xstring ).
  response->set_data( data   = pdf_xstring
                      length = l_pdf_len ).
  navigation->response_complete( ).
ENDMETHOD.
