  • Real Scenarios for Handler Interceptors

    Hi All:
    Was wondering if anyone can throw any light on servlet filters exact usage in real business scenarios ?
    What type of activities would you like to do using HandlerInterceptor's methods like preHandle(), postHandle() and afterCompletion()

    ALSO

    Why only preHandle() gets to return a boolean value whereas postHandle() and afterCompletion() are void ?

    Regards,
    Malleron
