File upload using commons-upload-file and tomcat 5.5

Question

Hi,
This is my first post and I hope that I post it at the right place.
I'm trying to upload a file using commons-upload-file and tomcat 5.5.
Is there a way to prevent submitting a big file, If I detect that the file being uploaded exceed a limit that I have fixed ?
i.e. I check the request length, if it's bigger than 1meg I cancel the whole thing and the big file is not transferred.
The problem that I get at the moment is that it seems that the file is transferred even if I close request inputstream or response outputstream. Any help would be appreciated !
Thank you

Well here is a snippet of my code:
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        long maxSize = 50000;
        boolean isMultipart = ServletFileUpload.isMultipartContent(request);
        if(isMultipart){
            // Create a new file upload handler
            ServletFileUpload upload = new ServletFileUpload();
            upload.setSizeMax(maxSize);
            try {
                upload.parseRequest(request);
            } catch (FileUploadException ex) {
                ex.printStackTrace();
                request.getInputStream().close();
                response.getWriter().print("blah");
                response.sendError(response.SC_INTERNAL_SERVER_ERROR);
                response.getOutputStream().close();
    }If the file is bigger than 50kb, it Throws the FileUploadException.
But whatever I do, It seems that there is still a connection between my browser and tomcat.. any clue ?
thanks
