Configuring the “Host” Header for Virtual Hosting
To support virtual hosting, configure the switch for Host header-based load balancing with the
following procedure:
1. Before you can configure header-based server load balancing, ensure that the switch has
already been configured for basic SLB with the following tasks:
n
Assign an IP address to each of the real servers in the server pool.
n
Define an IP interface on the switch.
n
Define each real server.
n
Assign servers to real server groups.
n
Define virtual servers and services.
For information on how to configure your network for server load balancing, see “Server Load
Balancing” on page 117 .
2. Turn on URL parsing for the virtual server for virtual hosting.
3. Define the host names.
4. Configure the real server(s) to handle the appropriate load balancing string(s).
To add a defined string:
where ID is the identification number of the defined string.
N OTE – If you don't add a defined string (or add the defined string “ any ”), the server will han-
dle any request.
