asp.net的启动顺序(转)

当网站启动时，初始化Global.asax.cs的构造方法，然后调用Application_Start，在调用构造方法，在调用Application_BeginRequest，再用Application_AuthenticateRequest，然后如果是一个新页面，则调用Session_Start，然后调用Application_EndRequest。

如果是新网页，则调用Session_Start，如果不是，只是刷新，则不调用。

当IIS重启或者session超时时，调用Session_End。

大体顺序如下：

2009-12-17 13:24:52 [DEBUG] - Application_Start
