     * Some filters need additional parameters from the request. All the 
     * necessary reading can occur in that method, as this method is called
     * after the request header processing is complete.
    public void setRequest(Request request);

     * Make the filter ready to process the next request.
    public void recycle();

     * Get the name of the encoding handled by this filter.
    public ByteChunk getEncodingName();

     * Set the next buffer in the filter pipeline.
    public void setBuffer(InputBuffer buffer);

     * End the current request.
     * @return 0 is the expected return value. A positive value indicates that
     * too many bytes were read. This method is allowed to use buffer.doRead
     * to consume extra bytes. The result of this method can't be negative (if
     * an error happens, an IOException should be thrown instead).
    public long end()
        throws IOException;

     * Amount of bytes still available in a buffer.
