asp.net静态页面生成实例

网页生成静态页面后对服务器的压力也打打减小，我们这里介绍一个asp.net静态页面生成的实例。目前网页html静态化是利用其它的动态技术生成html静态页面，还不是静态网站。因为的确是这样的，生成html静态网页有一定的好处。
     一、加快页面打开浏览速度，静态页面无需连接数据库教程打开速度较动态页面有明显提高；
     二、有利于搜索引擎优化seo教程，baidu、google都会优先收录静态页面，不仅被收录的快还收录的全；
     三、减轻服务器负担，浏览网页无需调用系统数据库；
     四、网站更安全，html页面不会受asp相关漏洞的影响；
     观看一下大一点的网站基本全是静态页面，而且可以减少攻击，防sql注入。数据库出错时，不影响网站正常访问。
     生成html文章虽操作上麻烦些，程序上繁杂些，但为了更利于搜索，为了速度更快些，更安全，这些牺牲还是值得的。
