Hello!
I wrote the ffollowing filter:
private FilterConfig    filterConfig    = null;

    /**
    * overwritten.
    */
    public void destroy() {
        filterConfig = null;

    }

    /**
    * filters parameters: ContentType and expires.
    */
    public void doFilter(ServletRequest arg0, ServletResponse arg1,
FilterChain arg2) throws IOException, ServletException {
        if (filterConfig == null)
            return;
        HttpServletRequest request = (HttpServletRequest) arg0;
        HttpServletResponse response = (HttpServletResponse) arg1;
        System.out.print(request.getContextPath());
        System.out.print(request.getContentLength());

        arg2.doFilter(request, response);
    }

    /* (non-Javadoc)
    * @see javax.servlet.Filter#init(javax.servlet.FilterConfig)
    */
    public void init(FilterConfig arg0) throws ServletException {
        this.filterConfig = arg0;

    }
and i get messege:
for ContextPath(): /servlet
for ContentLength(): -1.
How come I don't get any content?

Thank you
