IIS6默认情况下没有开启GZIP功能，需要我们手动配置，但他又没提供图形化配置功能，所以呀，像我这样的技术人才，都没考虑过使用他，昨天突然看到这个想到，也许对我有用，但从网上找了找，都是一堆手工操作方法，非常麻烦呀，不过以前研究过IIS的配置文件：C:\WINDOWS\system32\inetsrv\MetaBase.xml，所以呀，我知道只要是IIS的功能就可以通过修改这个文件来完成，所以呢，就对这个文件下手吧，根据网上提供的修改的地方，在网上搜索了一圈，找到一个类似ClickOnce 的东西，呵呵，重庆企业数据加密服务，我找的就是这个，所有操作都一键到位，重庆IT外包，只要执行一段VBS或CMD就配置好了，呵呵。
使用Gzip压缩会增大服务器CPU的使用率但可以通过压缩而减少服务器向客户端发送的数据,若使用了Gzip压缩IIS在向客户端发送数据时会自动检测，如果客户端浏览器支持IE6.0,firefox Gzip,则使用Gzip压缩后再传送数据，如果不支持，则使用常规方式发送。
所以，总结下他的优缺点，优：压缩传输，速度一般提高2倍。缺：CPU占用会有所提高，不过通过我的一点分析，GZIP只是在访问一个页时才会进行压缩，下次如果网页没有变动是不会压缩的，除非是使用压缩动态文件，这得实时的去压缩。
