Extending the Pipeline.NET Extensibility

Existing ASP.NET APIIHttpModule and IHttpHandler types

Expanded ASP.NET APIsNew HttpApplication Events

Extending the PipelineHandlers vs. Modules

Modules provide services to all requestsBasic Authentication moduleCompression module

Handlers provide services to specific extensionsISAPI handler (.dll)Static handler (.htm, .jpg, .gif, etc)

IIS 7 pipeline allows native and managed modules and handlers“Integrated” Application Pool mode

use the managed modules and handlers“Classic” Application Pool

IIS 6 style invocation of .NET

Modules & HandlersSaad LadkiProgram ManagerMicrosoft Corporation

Configuration System.NET + IIS7

Extending Configuration

IIS settings now live in ApplicationHost.config Can also be specified in web.config if delegation is allowed

All settings are schematized in XMLSchema files live in %windir%\system32\inetsrv\config\schema

Extending configurationStatic Configuration

Drop a .xml file into the schema directoryAdd a section to applicationHost.config

Dynamic Configuration

Add dynamic properties and behavior to configAHADMIN - Application Host Administration Interface

Implemented in %Windows%\System32\Inetsrv\nativerd.dllImplements IIS native configuration stackExposes a COM API

Exposes three interfaces for Dynamic ExtensibilityIAppHostPropertyExtensionIAppHostMethodExtensionIAppHostElementExtension
