Configuring the WSM using Device Manager

Configuring cookie-based preferential load balancing

Before configuring preferential load balancing, configure the WSM for server load balancing. See Configuring virtual server load balancing.

To configure cookie-based preferential load balancing:

1. Turn on URL parsing for the virtual server. See Configuring a virtual server. Set the following parameters on the virtual server:

­	Cookie Name

­	Cookie Offset

­	Cookie Length

­	Cookie Search

2. Enable cookie-based preferential load balancing on virtual service 80. See Configuring services for a virtual server. Set the following parameter.

­	HTTP SLB 1st = Cookie

3. Define the cookie values. See Defining a string for URL load balancing.
4. Configure the real server(s) to handle the cookie string(s). See Configuring a real server for URL-based load balancing.
   
   

   Note: If you do not add a defined string (or add the defined string any), the server will handle any request.

   
   
5. Enable DAM for the WSM or configure a proxy IP address on the client port. See Configuring direct access mode or Configuring a proxy IP address for a port.
   
   

   Note: If VMA is enabled, configure a proxy IP address on ports 1-8. If VMA is disabled, you need only one proxy IP address.

   
   
6. Enable proxy load balancing on the port used for cookie-based preferential load balancing. See Configuring ports for server load balancing. Set the following parameter:

­	Proxy IP Sate = Enabled Note: If Virtual Matrix Architecture (VMA) is enabled on the WSM, you can disable proxy IP on the remaining ports.
