c++로 웹에서 파일전송을 하려고 했는데 생각대로 잘 안됩니다.

#include <iostream.h>
#include <fstream.h>
#include <string.h>
 
int main () {
	std::string line;
	ifstream file("C:/file.mp3");
	if (file.is_open()) {
		int i = 0;
		long begin, end, size;
 
		begin = file.tellg();
		file.seekg (0, ios::end);
		end = file.tellg();
		size = end-begin;
		cout << "Content-Type: audio/mp3\n\n";
		cout << "Content-Length: " << size << "\n";
		cout << "Content-Disposition: attachment; filename=file.mp3\n";
		cout << "Cache-Control: no-store, no-cache, must-revalidate\n";
		cout << "Pragma: no-cache\n";
		cout << "Expires: -1\n";
 
		while(!file.eof()) {
			i++;
			if (i != 1) {
				cout << "\n";
			}
			getline(file, line);
			cout << line;
		}
		file.close();
	}
	else {
		cout << "Content-Type: text/html; charset=utf-8\n\n";
		cout << "Unable to open file";
	}
	return 0;
}
