Articles/Links on Asp.Net pipeline and internal request processing architecture

I am looking details on the internal working of asp.net architecture. The topics need to include the following:

1. Asp.Net Thread/Application Pools
2. HttpRuntime
3. HttpApplication - When and开发者_如何学Go how it is set up
4. How HttpContext is set up
5. How objects can passed along the pipeline using HttpContext.Current.Items
6. Why does modification of static variables requires locks in ASP.NET (advanced)
7. IIS 7 Integration Mode

This article from msdn magazine (Securely Implement Request Processing, Filtering, and Content Redirection with HTTP Pipelines in ASP.NET) describes many of the topics you listed.

I think article shared by Matthew is a good one. Here's another one that offers quite a bit insight - http://www.code-magazine.com/Article.aspx?quickid=0511061

With regards to IIS7 Integrated Pipeline and IIS in general, the IIS7 Resource Kit is fairly essential reference material. It's written by the IIS team and includes contributions from Mike Volodarsky (Programme Manager) and Carlos Aguilar Mares (Development Lead).

As a developer I have this book by my desk all the time.

The IIS.NET website is a pretty good resource too.
