如何配置一个HTTP服务器？
现在在网上找到如下可参考的代码

HINTERNET hssetion;
HINTERNET hConnect;
HINTERNET hRequrest;

hssetion = InternetOpenA( "httpDownload", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0 );
if ( NULL == hssetion )
{
// ::AfxMessageBox("open failed");
MessageBoxA(NULL,"open failed","caption",MB_OK);
return 1;
}

hConnect = InternetConnectA( hssetion, "127.0.0.1", INTERNET_DEFAULT_HTTP_PORT,
NULL, NULL, INTERNET_SERVICE_HTTP, 0, 0 );
if ( NULL == hConnect )
{
//::AfxMessageBox("connect failed");
MessageBoxA(NULL,"connect failed","caption",MB_OK);
return 0;
}

const char* pFileType = "*/*";
hRequrest = HttpOpenRequestA( hConnect, "GET", "musictop//new//1214793378.wma", "HTTP/1.1", NULL,
&pFileType, INTERNET_FLAG_RELOAD, 0 ); //<3> 类型为“文本型”。页面的地址,,<>

if ( NULL == hRequrest )
{
//::AfxMessageBoxA("open requrest failed");
MessageBoxA(NULL,"open requrest failed","caption",MB_OK);
return 1;
}

BOOL bBet = HttpSendRequest( hRequrest, NULL, 0, NULL, 0 );
if ( !bBet )
{
//::AfxMessageBoxA("send request failed");
MessageBoxA(NULL,"send request failed","caption",MB_OK);
return 1;
}
DWORD BufLen=4*1024*10;
char buffer[4*1024*10] = {0};
DWORD infoLen=4*1024*10;

DWORD dwIndex=0;
bool RetQueryInfo=HttpQueryInfo(hRequrest,
HTTP_QUERY_CONTENT_LENGTH,
buffer, &infoLen,
&dwIndex);
