9.2. About Global Valves
A Global Valve is a valve that is inserted into the request processing pipeline of all deployed applications. A valve is made global by being packaged and installed as a static module in JBoss EAP 6. Global valves are configured in the web subsystem.
Only version 6.1.0 and later supports global valves.
For instructions on how to configure Global Valves, see Section 9.5, “Configure a Global Valve”.
