Problem writing to output using servlet

Question

Hi All,
I created a servlet which reads file and writes to output . This works fine
when request protocol is http . But if protocol is changed to https servlet doesnt write to output. This servlet is deployed in secure environment as EAR project .But pops up error in popup
Internet explorer cannot download /ImageServlet/.... from the server....
requested site is unavailable.
Here is my servlet code
                    String key = request.getParameter("key");
                    if( key != null){
                         String[] keys = key.split(":");
                         System.out.println("request.getAuthType() :"+ request.getAuthType());
                         if(request.getAuthType() != null){
                         if(keys != null && keys.length >1){
                              ImageUtil imageUtil = new ImageUtil();
                              byte[] bytes = imageUtil.getDocumentContent(keys[0]);
                              ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
                              BufferedInputStream bis = new BufferedInputStream(bais);
                              ServletOutputStream out = response.getOutputStream();
                              BufferedOutputStream bos = new BufferedOutputStream(out);
                              response.reset();
                              if(keys[1].equalsIgnoreCase("doc") ) {
                                   response.setContentType("application/msword;charset=utf-8");
                                   response.setHeader("Content-Disposition","inline;filename=\"file.doc\";");
                              }else if(keys[1].equalsIgnoreCase("xls") ) {
                                   response.setContentType("application/vnd.ms-excel");
                                   response.setHeader("Content-Disposition","inline;filename=\"file.xls\";");
                              }else if(keys[1].equalsIgnoreCase("rtf") ){
                                   response.setContentType("application/msword");
                                   response.setHeader("Content-Disposition","inline;filename=\"file.rtf\";");                         
                              }else if(keys[1].equalsIgnoreCase("html") || keys[1].equalsIgnoreCase("htm")){
                                   response.setContentType("text/html");
                                   response.setHeader("Content-Disposition","inline;filename=\"file.html\";");                         
                              }else if(keys[1].equalsIgnoreCase("txt")){
                                   response.setContentType("text/plain");
                                   response.setHeader("Content-Disposition","inline;filename=\"file.txt\";");                         
                              //setting some response headers
                              response.setHeader("Cache-Control","no-store, no-cache, must-revalidate,post-check=0, pre-check=0"); //HTTP 1.1
                              response.setHeader("Pragma","no-cache"); //HTTP 1.0
                              response.setDateHeader ("Expires", 0);
                         int i;
                         while ( (i = bis.read(bytes)) > 0)
                              bos.write(bytes,0,i);
                         bos.flush();               
                         bos.close();
                         bis.close();
                         bais.close();
                         System.out.println("Has written");
                         }else{
                              log.error("Key is not good.");
               }else{
                    log.error("Please enter key for streaming.");
          }catch(Exception e)     {
log.error(e.toString());
e.printStackTrace();

Answer 1

Hi,
Found the solution for the problem. For some reason
response.setHeader("Cache-Control","no-store, no-cache, must-revalidate,post-check=0, pre-check=0"); //HTTP 1.1
                              response.setHeader("Pragma","no-cache"); //HTTP 1.0
                              response.setDateHeader ("Expires", 0);
These header settings were causing this issue. If I take out these settings then it works
FYI
Thankyou very much for all help
