1265 | The Response() function queues an HTTP response to this HTTP instance, similar to\r | |
f0ab5a81 | 1266 | Receive() function in the EFI TCP driver. When the HTTP response is received successfully,\r |
47f51a06 YT |
1267 | or if there is an error, Status in token will be updated and Event will be signaled.\r |
1268 | \r | |
1269 | The HTTP driver will queue a receive token to the underlying TCP instance. When data\r | |
1270 | is received in the underlying TCP instance, the data will be parsed and Token will\r | |
1271 | be populated with the response data. If the data received from the remote host\r | |
1272 | contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting\r | |
1273 | (asynchronously) for more data to be sent from the remote host before signaling\r | |
1274 | Event in Token.\r | |
1275 | \r | |
1276 | It is the responsibility of the caller to allocate a buffer for Body and specify the\r | |
1277 | size in BodyLength. If the remote host provides a response that contains a content\r | |
1278 | body, up to BodyLength bytes will be copied from the receive buffer into Body and\r | |
1279 | BodyLength will be updated with the amount of bytes received and copied to Body. This\r | |
1280 | allows the client to download a large file in chunks instead of into one contiguous\r | |
1281 | block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is\r | |
1282 | non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive\r | |
1283 | token to underlying TCP instance. If data arrives in the receive buffer, up to\r | |
1284 | BodyLength bytes of data will be copied to Body. The HTTP driver will then update\r | |
1285 | BodyLength with the amount of bytes received and copied to Body.\r | |
1286 | \r | |
1287 | If the HTTP driver does not have an open underlying TCP connection with the host\r | |
1288 | specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is\r | |
1289 | consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain\r | |
1290 | an open TCP connection between client and host.\r | |
