157/**\r
158 The Response() function queues an HTTP response to this HTTP instance, similar to\r
159 Receive() function in the EFI TCP driver. When the HTTP request is sent successfully,\r
160 or if there is an error, Status in token will be updated and Event will be signaled.\r
161\r
162 The HTTP driver will queue a receive token to the underlying TCP instance. When data\r
163 is received in the underlying TCP instance, the data will be parsed and Token will\r
164 be populated with the response data. If the data received from the remote host\r
165 contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting\r
166 (asynchronously) for more data to be sent from the remote host before signaling\r
167 Event in Token.\r
168\r
169 It is the responsibility of the caller to allocate a buffer for Body and specify the\r
170 size in BodyLength. If the remote host provides a response that contains a content\r
171 body, up to BodyLength bytes will be copied from the receive buffer into Body and\r
172 BodyLength will be updated with the amount of bytes received and copied to Body. This\r
173 allows the client to download a large file in chunks instead of into one contiguous\r
174 block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is\r
175 non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive\r
176 token to underlying TCP instance. If data arrives in the receive buffer, up to\r
177 BodyLength bytes of data will be copied to Body. The HTTP driver will then update\r
178 BodyLength with the amount of bytes received and copied to Body.\r
179\r
180 If the HTTP driver does not have an open underlying TCP connection with the host\r
181 specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is\r
182 consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain\r
183 an open TCP connection between client and host.\r

212 The Poll() function can be used by network drivers and applications to increase the\r
213 rate that data packets are moved between the communication devices and the transmit\r
214 and receive queues.\r

217 the underlying communications device fast enough to transmit and/or receive all data\r
