Class FailedRequestFilter

java.lang.Object

org.apache.catalina.filters.FilterBase

org.apache.catalina.filters.FailedRequestFilter

public class FailedRequestFilter
extends FilterBase

Filter that will reject requests if there was a failure during parameter parsing. This filter can be used to ensure that none parameter values submitted by client are lost.

Note that it has side effect that it triggers parameter parsing and thus consumes the body for POST requests. Parameter parsing does check content type of the request, so there should not be problems with addresses that use request.getInputStream() and request.getReader(), if requests parsed by them do not use standard value for content mime-type.
