IIS 7 for Developers

• Chris J.T. Auld
• Director Strategy and Innovation
• Intergen
• MSDN Regional Director

3
IIS7 Total Platform Extensibility

• Build and deploy custom server components
• Leverage powerful modular server architecture
• New native (C) server APIs
• Powerful and convenient managed (.NET) server
  features
• Extend the configuration and administration tools
• Leverage the new remote management capabilities
• Create new schematized configuration sections
• Plug into IIS Manager as a first-class citizen
  with custom UI

4
IIS6 Architecture

• Monolithic server implementation
• Limited customization
• Fixed functionality
• Limited ISAPI Filter extensibility

5
IIS7 Architecture

• Componentized server
• Pluggable modular functionality
• Small generic request pipeline
• Enables
• Lightweight servers
• Custom / specialized servers

6
IIS6 ASP.NET

• ISAPI Extension
• Only processes ASP.NET requests
• Runtime limitations
• Feature duplication

7
IIS7 ASP.NET Integration

• Classic Mode
• For compatibility
• Integrated Mode
• Can process all requests
• Enhanced functionality
• Higher fidelity notifications
• Developer extensible

8
.NET Extensibility

• Existing ASP.NET API
• IHttpModule and IHttpHandler types
• Expanded ASP.NET APIs
• New HttpApplication Events
• MapRequestHandler, LogRequest, PostLogRequest
• HttpRequest.Headers
• HttpResponse.Headers
• HttpResponse.DisableKernelCache
• HttpRequest.ServerVariables

9
Handlers vs Modules

• Modules provide services to all requests
• Basic Authentication module
• Compression module (etc)
• Handlers provide services to specific requests
• ISAPI 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 mode
• IIS 6 style invocation of .NET

Configuration System
Contoso.com root

• .NET IIS7

14
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 XML
• Schema files live in windir\system32\inetsrv\c
  onfig\schema
• Shared configuration allows multiple servers to
  use the same centralized configuration
• Extending configuration
• Static Configuration
• Drop a .xml file into the schema directory
• Add a section to applicationHost.config

16
Dynamic Configuration

• Allows you to add dynamic properties and add
  behavior to configuration
• AHADMIN - Application Host Administration
  Interface
• Implemented in Windows\System32\Inetsrv\nativerd
  .dll
• Implements IIS native configuration stack
• Exposes a COM API
• Exposes three interfaces for Dynamic
  Extensibility
• IAppHostPropertyExtension
• IAppHostMethodExtension
• IAppHostElementExtension

17
Benefits

• Tools for every need

• AppCmd.exe
• Command line to query and modify configuration
• IIS Manager
• User Interface for end users
• WMI
• New WMI provider to query and edit configuration
• Scripting
• AHADMIN is a new COM interface for managing
  configuration system
• Managed Code
• Microsoft.Web.Administration provides a simple
  managed API to edit configuration

18
IIS Manager

• Completely re-written using .NET Windows Forms
  and managed code
• IIS Manager is now easily extensible
• Add new feature pages
• Extend tasks for sites/applications
• More
• Extensibility Framework
• Microsoft.Web.Management.dll
• Transparent remoting over HTTPS

Summary

• IIS7 provides end-to-end extensibility for the
  managed code developer
• Take advantage of the IIS7 managed pipeline
• Extend configuration
• Build new features into the management tool
