IDHTTP能否上传大文件

[zhangjinwei_52]

我用IDHTTP上传一张超过20m的图片
sendbuffersize＝32768时提示socket error 10053
sendbuffersize＝10000000提示socket error 10054
不知道是说明原因，idhttp能否发送大文件呢？
以下是发送部分代码：
var
mpfSource : TIdMultiPartFormDataStream;
FResponseStream: TStringStream;


mpfSource := TIdMultiPartFormDataStream.Create;
FResponseStream := TStringStream.Create('');
try
try
with FIdHTTP do
begin
Request.ContentType := mpfSource.RequestContentType;

mpfSource.AddFormField('path', 'meinv/');
mpfSource.AddFile('upfile', 'C:/aaa.jpg', 'image/pjpeg'); //c:/aaa.jpg大小28m
mpfSource.Position := 0;
Post('http://localhost/fileup.asp', mpfSource, FresponseStream); //这里出错

Result := FresponseStream.DataString;
end;
except on E: Exception do
Result := UploadFailed;
end;
finally
mpfSource.Free;
FResponseStream.Free;
end;

晕倒，你先传一个几百K的试试，成功了就知道不是程序的问题了啊

以前只有超过几G才能这样.

4M以下的没有问题
