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.
