    Still there is an issue with re-open a file. Patch applied below to
    avoid it.
    
    Also iterate_post() always returns MHD_OK, because the app's logic
    driven
    from the value of con_info->answercode().
    And in case if fwrite() fails we also update the answer code & page  and
    MHD_post_process() overwrite them (fileioerror becomes postprocerror).
