5.4.1 Overview of distributing requests by the round-robin format
For distribution of requests in the round-robin format with a cluster configuration, use a worker definition called load balancer. The list of worker processes that act as the distribution destinations is defined in the load balancer. Based on this definition, requests are distributed to the worker processes in the round-robin format.
An HTTP request is distributed. The HTTP requests belonging to the same session, however, are distributed to the same worker as the previous distribution destination.
- Reference note
-
During the Web server integration, if you specify request distribution with the round-robin format in the redirector settings, the worker name will be added in the session ID of HttpSession. Also, regardless of whether the settings for adding the server ID are specified, the server ID will not be added in the session ID of HttpSession.
