417/**\r
418 The Response() function queues an HTTP response to this HTTP instance, similar to\r
34d00172 419 Receive() function in the EFI TCP driver. When the HTTP Response is received successfully,\r
cff298f4 420 or if there is an error, Status in token will be updated and Event will be signaled.\r
421\r
422 The HTTP driver will queue a receive token to the underlying TCP instance. When data\r
423 is received in the underlying TCP instance, the data will be parsed and Token will\r
424 be populated with the response data. If the data received from the remote host\r
425 contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting\r
426 (asynchronously) for more data to be sent from the remote host before signaling\r
427 Event in Token.\r
428\r
429 It is the responsibility of the caller to allocate a buffer for Body and specify the\r
430 size in BodyLength. If the remote host provides a response that contains a content\r
431 body, up to BodyLength bytes will be copied from the receive buffer into Body and\r
432 BodyLength will be updated with the amount of bytes received and copied to Body. This\r
433 allows the client to download a large file in chunks instead of into one contiguous\r
434 block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is\r
435 non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive\r
436 token to underlying TCP instance. If data arrives in the receive buffer, up to\r
437 BodyLength bytes of data will be copied to Body. The HTTP driver will then update\r
438 BodyLength with the amount of bytes received and copied to Body.\r
439\r
440 If the HTTP driver does not have an open underlying TCP connection with the host\r
441 specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is\r
442 consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain\r
443 an open TCP connection between client and host.\r

472 The Poll() function can be used by network drivers and applications to increase the\r
473 rate that data packets are moved between the communication devices and the transmit\r
474 and receive queues.\r
475\r
476 In some systems, the periodic timer event in the managed network driver may not poll\r
477 the underlying communications device fast enough to transmit and/or receive all data\r
478 packets without missing incoming packets or dropping outgoing packets. Drivers and\r
479 applications that are experiencing packet loss should try calling the Poll() function\r
480 more often.\r
