现在做web开发肯定离不开web服务器。知道各大网站用的都是什么服务器吗？
今天我就怀着这样一个好奇心写了个搜索web服务器类型的工具，具体代码就不贴了。
程序和代码在这里
主要思路是：
向一个网站发送HTTP请求，收到HTTP回复后检测其头部Server的值。
为了实现批量获取，还需要指定一系列网站的URL。
为了偷懒，我就从一个网页开始遍历其中所有的网址，然后获取其服务器类型。
光有数据还不行，还要对数据进行分析。我的策略是只分析服务器大的种类，具体版本就忽略了，这样就可以使用linq进行按服务器类型分组、排序等待
运行结果：
从www.hao123.com开始搜索，前三个用的最多的服务器是Apache(38.64%),nginx(21.36%),Microsoft IIS(17.27%).
然后还可以发现：Apache真的还有很多人用；尽管微软的IIS都有7.5的了，但6.0的IIS依旧还有很多在用。
下面是搜索到的服务器：
