Class RequestDumperFilter

java.lang.Object

org.apache.catalina.filters.RequestDumperFilter

All Implemented Interfaces:

javax.servlet.Filter

public class RequestDumperFilter
extends Object
implements javax.servlet.Filter

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.VerbatimFormmater is used.
