Using Multi-Homing To Access Multiple Resources; Domain-Based Multi-Homing - Novell ACCESS MANAGER 3.1 SP2 - ACCESS GATEWAY GUIDE 2010 Manual

Connection persistence is enabled by default. This allows the Access Gateway to send multiple
HTTP requests to the Web server to be serviced before the connection is closed. To configure this
option, see Section 1.6.2, "Configuring TCP Connect Options for Web Servers," on page
Session persistence is enabled whenever a second Web server is added to the list. This allows a
browser to persistently use the same Web server after an initial connection has been established.
This type of persistence is not configurable. For more information on persistent connections, see
Section 1.6.3, "Configuring Connection and Session Persistence," on page
6.2 Using Multi-Homing to Access Multiple
Resources
You can configure an Access Gateway to use one public IP address to protect multiple types of Web
resources. This is one of the major benefits of the Access Gateway, because it conserves valuable
resources such as IP addresses. This feature also makes an Access Gateway a multi-homing device
because it becomes a single endpoint supporting multiple back-end resources.
You can select to use only one multi-homing method, or you can use multiple methods. Select the
methods that meet the needs of your network and the resources you are protecting. The first proxy
service configured for a reverse proxy is always configured to use the DNS name of the Access
Gateway. Subsequent proxy services can be configured to use one of the following methods:
Section 6.2.1, "Domain-Based Multi-Homing," on page 183
Section 6.2.2, "Path-Based Multi-Homing," on page 185
Section 6.2.3, "Virtual Multi-Homing," on page 188
This section describes these multi-homing methods, then explains the following:

6.2.1 Domain-Based Multi-Homing

Domain-based multi-homing is based on the cookie domain. For example, if you have a cookie
domain of
