Class AbstractInMemoryThrottledSubmissionHandlerInterceptorAdapter

java.lang.Object
  org.springframework.web.servlet.handler.HandlerInterceptorAdapter
      org.jasig.cas.web.support.AbstractThrottledSubmissionHandlerInterceptorAdapter
          org.jasig.cas.web.support.AbstractInMemoryThrottledSubmissionHandlerInterceptorAdapter

All Implemented Interfaces:

org.springframework.web.servlet.HandlerInterceptor

Direct Known Subclasses:

InMemoryThrottledSubmissionByIpAddressAndUsernameHandlerInterceptorAdapter, InMemoryThrottledSubmissionByIpAddressHandlerInterceptorAdapter

public abstract class AbstractInMemoryThrottledSubmissionHandlerInterceptorAdapter
extends AbstractThrottledSubmissionHandlerInterceptorAdapter

Implementation of a HandlerInterceptorAdapter that keeps track of a mapping of IP Addresses to number of failures to authenticate.

Note, this class relies on an external method for decrementing the counts (i.e. a Quartz Job) and runs independent of the threshold of the parent.

Since:

3.0.5
