[jboss-jira] [JBoss JIRA] (WFLY-6778) Each Undertow server should expose a distinct SessionIdentifierCodec

Each Undertow server should expose a distinct SessionIdentifierCodec -------------------------------------------------------------------- Key: WFLY-6778 URL: https://issues.jboss.org/browse/WFLY-6778 Project: WildFly Issue Type: Bug Components: Clustering, Web (Undertow) Affects Versions: 10.0.0.Final Reporter: Paul Ferraro Assignee: Paul Ferraro Fix For: 11.0.0.Alpha1 Undertow exposes a single instance-id for the whole subsystem. This id is used by a load balancer to uniquely identify the node among other nodes in the load balancing group. However, this granularity is not correct. Undertow can define multiple servers, each with a unique set of listeners. From the perspective of the load balancer, these servers are distinct and thus must use distinct names. Thus, rather than installing a single SessionIdentifierCodec for the subsystem, we should install one instance per server.
