Where are HTTP modules and handlers registered?

The specific syntax for registering HTTP Modules and Handlers depends upon the web server that is powering the site. For the ASP.NET Development Server and Microsoft's IIS version 6.0 and earlier, HTTP Modules and Handlers are registered in the <httpModules> and <httpHandlers> sections, which appear within the <system.web> element. If you are using IIS 7.0 then they need to be registered in the <system.webServer> element's <modules> and <handlers> sections. Fortunately, you can define the HTTP Modules and Handlers in both places regardless of the web server being used. This option is the most portable one as it allows the same configuration to be used in the development and production environments regardless of the web server being used.
