将文件发送到HTTP服务器（C ++ Wininet）

Question

我有在我的HTTP服务器上上传小.txt个文件的代码：

#include <wininet.h>
#define BUF_SIZE 4096

void __fastcall TForm1::Button1Click(TObject *Sender)
{

 TStringList * list = new TStringList();
 AnsiString Path = "";

 if(OpenDialog1->Execute()) {

    Path =  "filename=\""+OpenDialog1->FileName+"\"";
    list->LoadFromFile(OpenDialog1->FileName);

 }

 char data[BUF_SIZE] = "";
 static char hdrs[] = "Content-Type: multipart/form-data; boundary=---------------------------7d82751e2bc0858";

 strcat(data,"-----------------------------7d82751e2bc0858");
 strcat(data,"\n");
 strcat(data,"Content-Disposition: form-data; name=\"files[]\"; ");
 strcat(data,Path.c_str());
 strcat(data,"\n");
 strcat(data,"Content-Type: application/octet-stream");
 strcat(data,"\n\n");
 strcat(data,list->Text.c_str());
 strcat(data,"\n");
 strcat(data,"-----------------------------7d82751e2bc0858");
 strcat(data,"\n");
 strcat(data,"Content-Disposition: form-data; name=\"user\"");
 strcat(data,"\r\n\r\n");
 strcat(data,"username");
 strcat(data,"\r\n");
 strcat(data,"-----------------------------7d82751e2bc0858");
 strcat(data,"\n");

 HINTERNET hSession = InternetOpen("MyAgent",INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
 HINTERNET hConnect = InternetConnect(hSession, "localhost",INTERNET_DEFAULT_HTTP_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 1);
 HINTERNET hRequest = HttpOpenRequest(hConnect, "POST", "new_upltest.php", NULL, NULL, NULL, 0, 1);

 HttpSendRequest(hRequest, hdrs, strlen(hdrs), data, strlen(data));

 delete list;
}

它工作正常，但现在我需要上传大文件（超过70-100 mb），可以是图像（.jpg，.png，.bmp）和其他文档类型（.pdf，.docx，等）。

是否可以使用此代码解决我的任务？我会对每个建议表示感谢......

P.S。我的IDE是C ++ Builder 6，但我认为没关系。
