HttpModule及其中的事件的执行顺序

HttpModule执行的顺序取决于web.config配置HttpModule的顺序,而HttpModule中事件的执行先后顺序与asp.net运行机制相关,具体执行顺序如下:

BeginRequest
AuthenticateRequest
AuthorizeRequest
ResolveRequestCache
AcquireRequestState
PreRequestHandlerExecute
PostRequestHandlerExecute
ReleaseRequestState
UpdateRequestCache
EndRequest


此外,有三个不确定的顺序:
PreSendRequestHeaders
PreSendRequestContent
Error

举个例子:
如果你在web.config配置了两个HttpModule,分别是HttpModuleA,HttpModuleB

这个事件执行的顺序如下:
HttpModuleA->BeginRequest
HttpModuleB->BeginRequest
HttpModuleA->AuthenticateRequest
HttpModuleB->AuthenticateRequest
HttpModuleA->AuthorizeRequest
HttpModuleB->AuthorizeRequest
...以此类推
