摘　　要：ASP.NET HttpApplication管线(即:Http管线)是使用截取过滤器(即:截获器)模式搭建的,然而在微软官方及可查的资料中,对HttpApplication管线的设计模式都描述得相当简约而且模糊,至于截取过滤器模式在HttpApplication管线中具体的实现策略涉及得更是寥寥。本文基于源代码,深入地清晰刻画出HttpApplication管线的设计模式及其详细的实现策略,揭示了其实现策略并非是微软官网上所声称那样使用了事件驱动,而是采用模板方法结合对象适配器的方式实现的。By means of intercepting Filter Pattern, the asp.net HttpApplication pipeline is constructed, however, the design pattern of the HttpApplieation pipeline are described sketchily and vaguely in the data of MSDN and that can been retrieved, not to mention the implementation strategy of intercepting Filter Pattern in the asp.net HttpApplieation pipeline. Based on the source code, in this paper this design pattern and its implementation strategy that is the template method combining with the object adapter are portrayed deeply and clearly.
