1123 | /**\r | |
1124 | The Response() function queues an HTTP response to this HTTP instance, similar to\r | |
1125 | Receive() function in the EFI TCP driver. When the HTTP request is sent successfully,\r | |
1126 | or if there is an error, Status in token will be updated and Event will be signaled.\r | |
1127 | \r | |
1128 | The HTTP driver will queue a receive token to the underlying TCP instance. When data\r | |
1129 | is received in the underlying TCP instance, the data will be parsed and Token will\r | |
1130 | be populated with the response data. If the data received from the remote host\r | |
1131 | contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting\r | |
1132 | (asynchronously) for more data to be sent from the remote host before signaling\r | |
1133 | Event in Token.\r | |
1134 | \r | |
1135 | It is the responsibility of the caller to allocate a buffer for Body and specify the\r | |
1136 | size in BodyLength. If the remote host provides a response that contains a content\r | |
1137 | body, up to BodyLength bytes will be copied from the receive buffer into Body and\r | |
1138 | BodyLength will be updated with the amount of bytes received and copied to Body. This\r | |
1139 | allows the client to download a large file in chunks instead of into one contiguous\r | |
1140 | block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is\r | |
1141 | non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive\r | |
1142 | token to underlying TCP instance. If data arrives in the receive buffer, up to\r | |
1143 | BodyLength bytes of data will be copied to Body. The HTTP driver will then update\r | |
1144 | BodyLength with the amount of bytes received and copied to Body.\r | |
1145 | \r | |
1146 | If the HTTP driver does not have an open underlying TCP connection with the host\r | |
1147 | specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is\r | |
1148 | consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain\r | |
1149 | an open TCP connection between client and host.\r | |
