今天研究一下HTTP协议，顺便分析了一下各大网站的WEB服务器，结果如下
分析的网站数量：194个，可能有重复的，其中比例
Apache:97,比例 59%
Microsoft IIS:51,比例 31%
Other:16,比例 10%
看来IIS还是老当益壮，加上现在的.net平台，还是占有相当大的比例的，Apache不愧当大的地位，其它的服务器也有不少。
有意思的是google全部使用自己的服务器GWS(Google Web Server),而baidu也来了个BWS(Baidu Web Server),但是他的网页以外的
服务仍然使用Apache,相比之下还是差了一些。据说baidu以前www.baidu.com都是用apache,现在也算有些进步了。
从行业来看，银行网站不少用的是IBM_HTTP_SERVER，实际上还是Apache,看来IBM做行业解决解决方案还是不错的。门户网站，例如sina，sohu之类都是apache,看来在性能、数据高速缓冲方面apache还是经得起考验的。对于不少企业、个人的网站IIS还是比较多。有的网站就分析不出来了，例如yahoo、3721系的估计是yahoo自己的，看不出来。
附上执行java程序源代码，下载SockedTest.rar
