通过URL取得html文件内容解决思路

通过URL取得html文件内容
遇到一道变态面试题目，要求不允许调用urlmon.dll和wininet.dll，已知一个URL，如何取得相对应的html文件里的部分字节内容？我有两个问题向大家求救？
　1.我想到一种方法，用WinExec启动ie,然后利用ie访问URL，不过不知道怎么传递那个URL   给ie.
    2.还有没有更好的方法，解决此问题？若能不下载文件就获得指定部分的内容更好。小弟的饭碗靠大家了！

[解决办法]
用sock连接80端口

发送请求

GET http://www.sina.com

题目应该是考察socket编程和http协议的...

socket可以通过域名访问的


#include <winsock2.h>
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <vector>
#define uchar unsigned char
#define DEFAULT_PORT 80
