Automatically Route Requests to Content Servers using IIS 7
Microsoft is demonstrating a new routing module for IIS 7. This module automatically routes requests to content servers based on HTTP headers and server variables. Administrators can also choose from one of six load balancing algorithms and can adjust the checks used to determine is a specific server is "healthy". Affinity with a content server can also be established on a client level, if the client accepts cookies, or by host name.
Management and Monitoring tools, including runtime statistics, are provided via an extension to the IIS Manager.
The Community Tech Preview requires the URL Rewrite Module.
