解決方法

I assume that happens when there is no ‘service’ param and CAS tries to render a successful generic login page. Correct? If so, that is a side effect that is caused by ‘terminateWebSessionListener’ bean defined in cas-servlet.xml. You could a) disable one b) set the ‘timeToDieInSeconds’ property to a higher value to remedy this annoyance, like so:

<bean id="terminateWebSessionListener" class="org.jasig.cas.web.flow.TerminateWebSessionListener" 
      p:timeToDieInSeconds="10"/>
