    Partial revert of 82abaee62f000d379646ee412af45a1f8a1ddc87
    
    No need to process part of code if some variables length are zeros.
    Non-NULL pointers can point to zero-length strings, but if pointer is
    NULL the length is always zero.
    For example 'req_body' could be not be NULL, but as long as
    'req_body_size' is zero, no chunk must be added.
