Overview
The HttpClusterServlet provided with WebLogic Server proxies requests from a
WebLogic Server acting as an HTTP server to server instances in a WebLogic Server
cluster. The
HttpClusterServlet provides load balancing and failover for the
proxied HTTP requests. For additional information on servlets and clustering, see
Understanding HTTP Session State Replication at
http://e-docs.bea.com/wls/docs61/cluster/servlet.html.
To proxy requests to a single server instance rather than to a cluster, use the
HttpProxyServlet. For more information, see “Proxying Requests to Another HTTP
Server” on page 9-1.
