This function is to call proper functions according to the VIO argument. If it's read_vio, which means reading request from client_vc, call state_read_request_from_client. If it's write_vio, which means sending response to client_vc, call state_send_response_to_client. If the event is TS_EVENT_VCONN_EOS, which means the client closed socket and thus implies the client drop all jo

   which means the client closed socket and thus implies the client
