  In my apache server i have a permanent redirection which redirect all wiki traffic on https.
  When i try to download a file (via fetch.php) Firefox works but Explorer not, it reports an error saying that the file is not there.
  If i disable https in _media urls it starts working again.

  I too have the exact same problem.. firefox, konq work fine for me.. just not IE. hitting the page with normal http port 80 traffic works

  It's a common problem when dealing with http-Headers in your script (so the webserver itself is not able to fix a long known SSL-incompatibility of Microsoft Internet Explorer).
  
  I solved it by myself in /lib/exe/fetch.php as follows (quick and dirty taken from my PHProjekt code bugfix to Dokuwiki 2005-07-01):
  ----------------------
   //FIXME set sane cachecontrol headers
   //FIXME handle conditional and partial requests
  
   //send file
   header("Content-Type: $MIME");
   header('Last-Modified: '.date('r',filemtime($FILE)));
   header('Content-Length: '.filesize($FILE));
   header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
   header ("Pragma: public");                                                   // [added line]
  
  
   //application mime type is downloadable
   if(substr($MIME,0,11) == 'application'){
     header('Content-Disposition: attachment; filename="'.basename($FILE).'";');  // [changed: add ';' at the end]
   }
  
   $fp = @fopen($FILE,"rb");
   if($fp){
      if (filesize($FILE) <= 2000000) {                  // [added line: bugfix PHP 5.04 fpassthru-Bug]
         fpassthru($fp); //does a close itself
      } else {                                           // [added line: bugfix PHP 5.04 fpassthru-Bug]
          while (strlen($data = fread($fp, 256*1024))) { // [added line: bugfix PHP 5.04 fpassthru-Bug]
              echo $data;                                // [added line: bugfix PHP 5.04 fpassthru-Bug]
          }                                              // [added line: bugfix PHP 5.04 fpassthru-Bug]
          fclose($fp);                                   // [added line: bugfix PHP 5.04 fpassthru-Bug]
      }                                                  // [added line: bugfix PHP 5.04 fpassthru-Bug]
   }else{
     header("HTTP/1.0 500 Internal Server Error");
     print "Could not read $FILE - bad permissions?";
   }
  
  -----------------
  Don't know if that works via http and which of the changed things are really neccessary - but this way it works well.
  
  Happy coding : Michael

  yes, this is a known bug in MSIE - it should be overriden as above
  
  now confirmed it works on HTTPS installation

  For me, (Apache/2.0.55 (Unix) PHP/4.4.1) bugfix woks fine with
  ------------------------------------------------
  header ("Pragma: public"); // [added line]
  
  //application mime type is downloadable
  if(substr($MIME,0,11) == 'application'){
  header('Content-Disposition: attachment; filename="'.basename($FILE).'";'); // [changed: add ';' at the end]
  }
  
  --------------------------------------------
  no other code (as shown above) is needed
