  • 启用IIS6的GZIP功能,提高网站打开速度,减少带宽占用【转】

            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,我找的就是这个,所有操作都一键到位,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。
