public class RequestDumperFilter extends GenericFilter

Implementation of a Filter 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.

When using this Filter, it is strongly recommended that the org.apache.catalina.filter.RequestDumperFilter logger is directed to a dedicated file and that the org.apache.juli.VerbatimFormatter is used.
