java.lang.Object org.apache.catalina.valves.ValveBase org.apache.catalina.valves.RequestDumperValve
Implementation of a Valve that logs interesting contents from the specified Request (before processing) and the corresponding Response (after processing). It is especially useful in debugging problems related to headers and cookies.
This Valve may be attached to any Container, depending on the granularity of the logging you wish to perform.
Note that this Valve sets the character encoding of the request to the default (ISO-8859-1) if it's the first thing invoking request.getParameterNames, which is usually the case. If you're running in an environment where this encoding is problematic, consider using another debugging approach such as a Filter that reproduces this Valve's functionality.
For a similar mechanism that is portable to all Servlet 2.4 containers, check out the "RequestDumperFilter" Filter in the example application (the source for this filter may be found in $CATALINA_HOME/webapps/examples/WEB-INF/classes/filters.
