Default HttpModule in ASP.NET systems:

Default Authentication Module ensures that the Authentication object exists in the context. Cannot inherit this class.

FileAuthorizationModule verifies that the remote user has NT access to the requested file. Cannot inherit this class.

Forms Authentication Module enables the ASP.NET application to use Forms authentication. Cannot inherit this class.

Passport Authentication Module provides wrapper around Passport Authentication services. Cannot inherit this class.

SessionStateModule provides session state services for ASP.NET applications.

UrlAuthorizationModule provides URL-based authorization services to allow or deny access to specified resources. Cannot inherit this class.

Windows Authentication Module enables the ASP.NET application to use Windows/IIS authentication. Cannot inherit this class

The default HttpModule of these systems is configured in the file machine.config, and the relationship with the web.config we used when developing is: when ASP.NET FRAMEWORK starts to process a Http Request, it will load the web.config file of the machine.config and the directory where the request page is located. If you configure your own HttpModule in the machine, you can still remove this mapping relationship in the web.config file of the page.
