本来是想实现ssl连接的，但是弄了好久都不成功，就索性不做了，等以后有能力再做了。所以这一小节就是本次的最后一节了。就简单的说几个注意点。
1.加个配置文件
使用单例模式，使用一个类，该类保存一些信息，例如一个配置类的一个属性为PAGE404的字符串，该字符串保存一个文件地址，然后我们的Page_404函数就可以用access判断PAGE404这个字符串对应的文件是否存在，如果存在那么如果是404页面那么就cat这个文件，而不是默认的404函数里面的页面。还有个端口什么的都是通过一个类似宏定义一样，代替程序中的魔数。还有各种配置的就不多说了。
2.访问控制
这个就更简单了，通过一个配置文件读取运行的IP，和拒绝的IP，然后在WebServer::ServerAccept()函数中可以判断，在这个函数中可以获取到连接进来的IP地址，然后可以通过这个IP地址进行约束。具体也不是很难。
3.siege性能测试
这个就是本小节的重点了。(这里要说明的是我这个服务器性能差的很，求不吐槽。)
