Paul Ferraro created WFLY-10485: ----------------------------------- Summary: Distributed web sessions fail to replicate if Undertow configured with custom session ID alphabet Key: WFLY-10485 URL: https://issues.jboss.org/browse/WFLY-10485 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 13.0.0.Beta1 Reporter: Paul Ferraro Assignee: Paul Ferraro The wildfly-clustering-web-undertow module currently assumes that session IDs generated by Undertow are marshallable using Base64.getUrlDecoder(). Undertow 2.0.x added support for customizing the alphabet using a system property. Any user doing so will be unable to use distributed web session manager, as the generated session IDs will fail to marshal at runtime. At the very least, we should detect the use of this system property and disable the session ID marshalling optimization. At most, we can adapt the marshalling optimization to use the custom alphabet. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
