  Receive() function in the EFI TCP driver. When the HTTP response is received successfully,\r

\r
  The HTTP driver will queue a receive token to the underlying TCP instance. When data\r
  is received in the underlying TCP instance, the data will be parsed and Token will\r
  be populated with the response data. If the data received from the remote host\r

  Event in Token.\r
\r
  It is the responsibility of the caller to allocate a buffer for Body and specify the\r
  size in BodyLength. If the remote host provides a response that contains a content\r
  body, up to BodyLength bytes will be copied from the receive buffer into Body and\r
  BodyLength will be updated with the amount of bytes received and copied to Body. This\r
  allows the client to download a large file in chunks instead of into one contiguous\r
  block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is\r
  non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive\r
  token to underlying TCP instance. If data arrives in the receive buffer, up to\r
  BodyLength bytes of data will be copied to Body. The HTTP driver will then update\r
  BodyLength with the amount of bytes received and copied to Body.\r
\r
  If the HTTP driver does not have an open underlying TCP connection with the host\r
  specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is\r
  consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain\r
  an open TCP connection between client and host.\r
