+ Because ControllerHandle may have been previously started by the same

+/**
+ 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.
