Securely Implement Request Processing, Filtering, and Content Redirection with HTTP Pipelines in ASP.NET

摘要

ASP.NET is a flexible and extensible framework for server-side HTTP programming. While most people think of ASP.NET in terms of pages served, there is a lower-level Infrastructure sitting beneath this page model. The underlying plumbing is based on a pipeline of app, module, and handler objects. Understanding how this pipeline works is key if you want to get the most out of ASP.NET as an HTTP server platform, while making your process more efficient, and keeping your server secure. This article introduces the architecture of the pipeline and shows how you can use it to add sophisticated functionality to an ASP.NET-based app.
