It does not work. Here is my code:

public Reply outgoingFilter(Request request, Reply reply)
  throws HttpException
          if ((reply.getStatus() < 400) && (reply.getStatus() != 301)
            && (reply.getStatus() != 307))
           byte[] content = getFileContent(request, reply);
           // make a clone of this content to set it in the reply
           byte[] clone = new byte[content.length];
           reply.setStream(new ByteArrayInputStream(clone));
           // ok it's done ... Send the event to the listenr
     return reply;

private static byte[] getFileContent(Request request, Reply reply)
        byte [] buf1 = new byte [1024];
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int inlen;
        try {
            InputStream stream = reply.getInputStream();
            while(( inlen = stream.read(buf1,0,buf1.length)) > 0){
        } catch(IOException ioe){
            Logger.trace("I/O Proxy Error while retrieving the content of: "
        return baos.toByteArray();

I don't know which method of the reply I should call to set the stream to
higher stacks. When I run, i got no pages and I have the following error:
