Message	Warning: Cannot modify header information - headers already sent by (output started at 
/www/htdocs/includes/file.inc:1965) in _drupal_session_delete_cookie() 
(line 466 of /www/www-live/drupal.sanger.ac.uk/htdocs/includes/session.inc).

function _drupal_session_delete_cookie($name, $secure = NULL) {
.....
466: setcookie($name, '', REQUEST_TIME - 3600, $params['path'], $params['domain'], $params['secure'], $params['httponly']);


function file_transfer($uri, $headers) {
......
  drupal_send_headers();
  $scheme = file_uri_scheme($uri);
  // Transfer file in 1024 byte chunks to save memory usage.
  if ($scheme && file_stream_wrapper_valid_scheme($scheme) && $fd = fopen($uri, 'rb')) {
    while (!feof($fd)) {
1965: print fread($fd, 1024);

Why is this cookie being deleted after the headers and file contents for a file download have been sent for an anonymous user?

    Is this still applicable for Drupal 9 and 10? If so, we need steps to reproduce, ideally with a failing test. We should update the issue summary to use the standard template also.

    More information on this was asked for 8 months ago, specifically if this is still a problem, and none has been supplied.

    Therefore, closing as outdated. If this is incorrect reopen the issue, by setting the status to 'Active', and add a comment explaining what still needs to be done.

    Thanks!
