      Either
      A) don't deploy a / or smaller path
      B) Use ProxyPass/ProxyPassReverse in Apache to map / to a difference context in JBoss/mod_cluster but don't actually use / in JBoss.

      A server configured for failover with an application deployed in a subdirectory such as <code>/webapp</code>, and another application deployed in <code>/</code>, occasionally caused an error. This was because the failed-over application tried to deploy in <code>/</code> instead of <code>/webapp</code>. This situation has been fixed, and failover now occurs as expected.

    Description

      Let's say for example that /webapp and / is mapped in mod_cluster and there are two JBoss instances. If in one JBoss instance you undeploy the /webapp, you would expect mod_cluster to failover to the other JBoss instance.

      However, this is not the case, mod_cluster will instead select the lesser context, the root context / and service the request from /webapp on the / context.

      The logic only tests for ENABLE and DISABLE the STOP is not tested.

      The failover of a context will only work currently if / or any smaller path is not deployed

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
