Response和Request的 高级使用

Question

_Response.AddHeader("Accept-Ranges", "bytes");
_Response.Buffer = false;

这个是什么意思?

if (_Request.Headers["Range"] != null)
                {
                    _Response.StatusCode = 206;
                    string[] range = _Request.Headers["Range"].Split(new char[] { '=', '-' });
                    startBytes = Convert.ToInt64(range[1]);
                }

这又是什么意思啊

_Response.AddHeader("Content-Length", (fileLength - startBytes).ToString());

_Response.AddHeader("Connection", "Keep-Alive");
                _Response.ContentType = "application/octet-stream";
                _Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(_fileName, System.Text.Encoding.UTF8));

这些东西都不懂，有谁可以帮我解释下这些代码嘛？

Answer 1

MSDN上API写的很清楚。

Answer 2

这些都是请求的包头，如缓存、编码等
