Modified: src/java/org/apache/turbine/pipeline DefaultActionValve.java
Added: src/java/org/apache/turbine/pipeline
DefaultACLCreationValve.java DefaultLoginValve.java
DefaultSessionTimeoutValve.java
DefaultSessionValidationValve.java
Log:
- some breaking apart of the the big valves into smaller valves, some
regrouping may occur, but i'd would like try and group by concern, for
example security. it should be easy to use turbine without security.
