Is sticky load balancing supported?
Not for PE and SE. The Sun ONE Application Server reverse proxy plug-in (web connector) cannot channel HTTP requests based upon Session ID. However, if you use a load balancing facility from another vendor that will do the sticky load balancing, you can deploy it in front of your application servers (or web servers, if the Sun ONE Application Server reverse proxy plug-in is installed) to provide sticky load balancing. Yes for EE. Sun ONE Application Server 7, Enterprise Edition load balancer uses a sticky round robin algorithm to load balance incoming HTTP and HTTPS requests. The load balancer plug-in uses the following methods to determine session stickiness: • Cookie-based method—The load balancer plug-in uses a separate cookie to record the route information. The browser must support cookies. • Explicit URL rewriting method—Sticky information is appended to the URL. Works even if the browser does not support cookies.
