Iis7 server total platform extensibility l.jpg

IIS7 ServerTotal platform extensibility

  • Customize the server

  • Build and deploy custom server components

    • Leverage powerful modular server architecture

    • Robust native (C++) server features

    • Powerful managed (.NET) server features


Iis6 architecture l.jpg

IIS6 Architecture

  • Monolithic server implementation

    • Limited customization

    • Fixed functionality

  • ISAPI Filter / Extension extensibility

    • Limited

    • Difficult, error prone


Iis7 architecture l.jpg

IIS7 Architecture

  • Componentized server

    • Modular features

    • Generic request pipeline

  • Enables

    • Lightweight servers

    • Custom / specialized servers


Iis7 extensibility l.jpg

IIS7 Extensibility

  • Public module extensibility model

    • DLL factory

    • Class-based C++ API

    • Rich object model

  • Enables

    • Complete extensibility

    • Simpler, robust code


Iis7 modules vs isapi filters and extensions l.jpg

IIS7 Modulesvs. ISAPI Filters and Extensions

  • More Powerful

    • MUCH Richer API

    • More granular notifications

  • Easier to write and more robust

    • Object-oriented C++

    • Key patterns simplified

  • Easier to manage

    • Consistent feature management

    • Granular enablement

Iis6 asp net integration l.jpg

IIS6 ASP.NET Integration

  • ISAPI Extension

    • Only processes ASP.NET requests

    • Runtime limitations

      • ISAPI

      • ordering

    • Feature duplication

      • Authentication

      • Handler mapping

      • Custom errors


Iis7 asp net integration l.jpg

IIS7 ASP.NET Integration

  • Two modes:

    • ISAPI (compat)

    • Integrated

  • Integrated mode

    • .NET modules plug directly into server

    • Process all requests

    • Full runtime fidelity


Iis7 net extensibility future of asp net development l.jpg

IIS7 .NET ExtensibilityFuture of ASP.NET Development

  • Existing ASP.NET 2.0 API

    • IHttpModule and IHttpHandler types

    • Existing API connected to server objects

  • Bonus: API additions

    • Response header enumeration

    • Manipulate Request headers

    • Manipulate Server Variables

  • Configuration

    • ISAPI vs. Integrated mode per app-pool

    • Unified <modules>, <handlers> configuration

Iis7 development c or net l.jpg

IIS7 DevelopmentC++ or .NET?

  • .NET: nice and easy

    • Finally can do almost anything

    • Multi-language RAD with .NET Framework

    • Rich ASP.NET APIs

    • Sandboxed deployment (CAS)

  • C++: down to the metal

    • More control over the system

    • Higher performance

    • Specific scenarios: non-request, cross-app


Compatibility existing extensibility just works l.jpg

CompatibilityExisting extensibility just works

  • Server

    • Built-in account

    • IIS6 Worker Process Isolation

    • Buffering on by default

  • ASP.NET applications

    • ASP.NET 1.1, ASP.NET 2.0

    • 2 modes: ISAPI, Integrated

  • ISAPI filters and extensions

    • Read-raw notifications cut
