‘** 实现文件下载函数 **

Const loadfilesize=32768 ‘32KB,也可取其它值，单位：字节
‘在给path赋值后，其最终值必定是该图片在服务器端存储器上的绝对路径，如 C:\Inetpub\wwwroot\pic\help.gif
‘因为 server.MapPath 取得的只是站点根目录的路径，所以在后面还应加上文件所在的文件夹再加文件名
‘例如：要下载的文件 setup.exe 在根目录的 download 文件夹下,则 path = server.MapPath("download/"&filename)
‘***********************************
‘测试用
‘response.Write(path)
‘response.Write(filename)
‘response.End()
