Server Affinity Page

Updated: November 5, 2009

Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista

Application Request Routing (ARR) provides client and host name affinity features that enable you to provide stickiness between clients and servers.

Host name affinity lets you map a host name to a server so that all requests for the same host name are routed to the same server. Client affinity is used to map a client to an application server behind ARR for the duration of the client session. A load balance algorithm is used for the first request from the client. Subsequent requests from the same client are routed to the application server for the duration of the client session.

noteNote
You can use client affinity and host name affinity together. When both are configured, if a host name is affinitized to multiple servers, client affinity is applied within the allocated and host name affinitized application servers.

 

Element Name Description

Host name affinity provider

Use the list to select the provider to use to affinitize host names. There are two options:

  • Microsoft.Web.Arr.HostNameRoundRobin – Allocates and affinitizes host names so that they are distributed evenly.

  • Microsoft.Web.Arr.HostNameMemory – Allocates and affinitizes host names based on memory information calculated from performance counters.

Time-out (minutes)

Specifies the time, in minutes, that a request can attempt to connect to the server.
