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.
