/**
The Response() function queues an HTTP response to this HTTP instance, similar to
Receive() function in the EFI TCP driver. When the HTTP request is sent successfully,
or if there is an error, Status in token will be updated and Event will be signaled.
The HTTP driver will queue a receive token to the underlying TCP instance. When data
is received in the underlying TCP instance, the data will be parsed and Token will
be populated with the response data. If the data received from the remote host
contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
(asynchronously) for more data to be sent from the remote host before signaling
Event in Token.
It is the responsibility of the caller to allocate a buffer for Body and specify the
size in BodyLength. If the remote host provides a response that contains a content
body, up to BodyLength bytes will be copied from the receive buffer into Body and
BodyLength will be updated with the amount of bytes received and copied to Body. This
allows the client to download a large file in chunks instead of into one contiguous
block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
token to underlying TCP instance. If data arrives in the receive buffer, up to
BodyLength bytes of data will be copied to Body. The HTTP driver will then update
BodyLength with the amount of bytes received and copied to Body.
If the HTTP driver does not have an open underlying TCP connection with the host
specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is
consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain
an open TCP connection between client and host.
@param[in] This Pointer to EFI_HTTP_PROTOCOL instance.
@param[in] Token Pointer to storage containing HTTP response token.
