ProxyErrorOverride=On causes workers in error state after 500 errors --------------------------------------------------------------------- Key: MODCLUSTER-505 URL: https://issues.jboss.org/browse/MODCLUSTER-505 Project: mod_cluster Issue Type: Bug Components: Native (httpd modules) Affects Versions: 1.3.2.Final, 1.2.12.Final Reporter: Aaron Ogburn Assignee: Jean-Frederic Clere Fix For: 1.2.14.Final, 1.3.5.Final When a VirtualHost uses ProxyPass to proxy traffic to the backend and uses ProxyErrorOverride to host custom error pages on Apache httpd side, when the backend replies with a 50x error code mod_proxy/mod_cluster marks that worker as down, breaking session stickiness. This behaviour is quite similar to have failonstatus=500 for example.
