Flash interceptor (
FlashInterceptor ) possibly with
FlashResult
allows current action to be available even after a redirect. It does this by
saving the current action into http session and pushing it back into the stack
next request, resulting in the nett effect of the action and its related information
being available across redirect.
There's no intended extension points
<!-- Usage 1: (Using only Flash interceptor) -->
<action name="store" ...>
<interceptor-ref name="flash">
<param name="operation">Store</param>
</interceptor-ref>
<interceptor-ref name="defaultStack" />

</action>
<action name="retrieve">
<interceptor-ref name="flash">
<param name="operation">Retrieve</param>
</interceptor-ref>
<interceptor-ref name="defaultStack" />
<result>pageWhereWeNeedFlashActionStored.jsp</result>
</action>

<interceptor-ref name="flash">
