Administration
• New Administration UI
• New Command Line Utility appcmd.exe
• New Managed DLL –
Microsoft.Web.Administration
• Can be Delegated
• Server can be managed Remotely
Andrew Westgarth - http://www.andrewwestgarth.co.uk/Blog - [email protected]
Delegated Administration
• Server Administration can be delegated via
configuration
– Allows Administrators to enable others to control
aspects of configuration
• Remote Administration of IIS in Windows
Server 2008

Demo – IIS7 Administration
• Administration UI and AppCmd
• Review of Microsoft.Web.Administration

Componentization
• IIS7 Now Fully Modular
• Can have very small server footprint
• Customise to only install/enable features you
want to have running
• Therefore only patch what you need/use

Configuration
• No more Metabase!!!!
• Compatability – old metabase pushed to new
config – same property names
• Central File – ApplicationHost.config
– Strongly Typed Schema
– Use same methodology as ASP.Net .config files
• Distributed Configuration

Demo - Configuration
• Let’s take a look at the new configuration
system.

Extensibility Model
• IIS6 – ISAPI Filter and Extensions
• IIS7 – Brand New Win32 Native Interface
– All IIS Modules written using this interface
– IIS Team uses this API just like you WILL!
– Full ASP.Net 2.0 Support
– IHttpModule available supported today!
– ASP.Net 2.0 Handlers run same as today
– IIS Manager (UI)
– Extend using .Net 2.0
– Diagnostics
– Add own events directly into pipeline (System.Diagnostics)
Andrew Westgarth - http://www.andrewwestgarth.co.uk/Blog - [email protected]
ASP.Net HttpHandlers and HttpModules
• HttpHandler
– Similar to ISAPI extensions
– Can be called via url
– Act as target for incoming requests
• HttpModules
– Plug into the ASP.Net request processing pipeline
– Registered for certain events
– As the event occurs the ASP.Net invokes the
module so it can handle the request
Andrew Westgarth - http://www.andrewwestgarth.co.uk/Blog - [email protected]
Demo Extensibility
• Build Image Copyright Handler
• Build Module and Integrate with IIS7 Admin
Andrew Westgarth - http://www.andrewwestgarth.co.uk/Blog - [email protected]
Troubleshooting and Diagnostics
• Real Time State Information Available
– Current Processes Running
– Application Pools Process ID
– Currently executing requests
– AppDomains loaded
• Real-time starting and stopping of sites
• Failed Request Tracing
• Extensive Custom Errors
Andrew Westgarth - http://www.andrewwestgarth.co.uk/Blog - [email protected]
Failed Request Tracing
•
•
•
•
Traces all requests through Pipeline
Automatically Enabled on IIS7
Easily identify failing, stuck requests
Identifies time take in each module, helping
analyzing long running requests
Andrew Westgarth - http://www.andrewwestgarth.co.uk/Blog - [email protected]
Custom Errors
• Much more detailed
– Language specific (Accept-Encoding)
– Time
– URL
– Current Module
– Response Status, Sub-Status
– More Information – Detailed steps to fix problem
where available

Demo Troubleshooting
• Custom Error Pages
• Failed Request Tracing
Andrew Westgarth - http://www.andrewwestgarth.co.uk/Blog - [email protected]
Unified Platform for Web Services and
WCF
• Host WCF Services using Windows Activation
Service (WAS)
• Supports Non-HTTP Protocols such as
– Named Pipes
– TCP
– MSMQ
• Provides features for idle-time management,
health monitoring, process recycling
