    Description

      I'm trying to read the incoming HTTP Servlet request attribute when using AJP with the Apache module "mod_proxy_ajp", but I receive null as a result.

      This works on JBoss EAP 7.3.0 (Undertow 2.0.28.SP1-redhat-00001).

      It does not work on neither JBoss EAP 7.4.0 (Undertow 2.2.5.Final-redhat-00001) nor WildFly 24.0.1 (Undertow 2.2.8.Final).
