      */ 
     String agent = request.getHeader("USER-AGENT"); 
     try { 
       if ((agent != null) && (-1 != agent.indexOf("MSIE"))) { 
         String newFileName = URLEncoder.encode(filename, "UTF-8"); 
         newFileName = StringUtils.replace(newFileName, "+", "%20"); 
         if (newFileName.length() > 150) { 
           newFileName = new String(filename.getBytes("GB2312"), "ISO8859-1"); 
           newFileName = StringUtils.replace(newFileName, " ", "%20"); 
         } 
         return newFileName;
