1297 The Response() function queues an HTTP response to this HTTP instance, similar to
1298 Receive() function in the EFI TCP driver. When the HTTP response is received successfully,
1299 or if there is an error, Status in token will be updated and Event will be signaled.
1301 The HTTP driver will queue a receive token to the underlying TCP instance. When data
1302 is received in the underlying TCP instance, the data will be parsed and Token will
1303 be populated with the response data. If the data received from the remote host
1304 contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
1305 (asynchronously) for more data to be sent from the remote host before signaling
1308 It is the responsibility of the caller to allocate a buffer for Body and specify the
1309 size in BodyLength. If the remote host provides a response that contains a content
1310 body, up to BodyLength bytes will be copied from the receive buffer into Body and
1311 BodyLength will be updated with the amount of bytes received and copied to Body. This
1312 allows the client to download a large file in chunks instead of into one contiguous
1313 block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
1314 non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
1315 token to underlying TCP instance. If data arrives in the receive buffer, up to
1316 BodyLength bytes of data will be copied to Body. The HTTP driver will then update
1317 BodyLength with the amount of bytes received and copied to Body.
1319 If the HTTP driver does not have an open underlying TCP connection with the host
1320 specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is
1321 consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain
1322 an open TCP connection between client and host.
