public class TokenSessionStoreInterceptor extends TokenInterceptor
This interceptor builds off of the TokenInterceptor
, providing advanced logic for handling invalid tokens.
Unlike the normal token interceptor, this interceptor will attempt to provide intelligent fail-over in the event of
multiple requests using the same session. That is, it will block subsequent requests until the first request is
complete, and then instead of returning the invalid.token code, it will attempt to display the same response
that the original, valid action invocation would have displayed if no multiple requests were submitted in the first
place.
NOTE: As this method extends off MethodFilterInterceptor, it is capable of
deciding if it is applicable only to selective methods in the action class. See
MethodFilterInterceptor
for more info.

Example code:
<action name="someAction" class="com.examples.SomeAction"> <interceptor-ref name="tokenSession/> <interceptor-ref name="basicStack"/> <result name="success">good_result.ftl</result> </action> <-- In this case, myMethod of the action class will not get checked for invalidity of token --> <action name="someAction" class="com.examples.SomeAction"> <interceptor-ref name="tokenSession> <param name="excludeMethods">myMethod</param> </interceptor-ref name="tokenSession> <interceptor-ref name="basicStack"/> <result name="success">good_result.ftl</result> </action>
