Step 1: Define Cache Key and invalidation variable.

  • Click on Web Stimulus Data Packet control.
  • Type an expression that represents the cache key in its Property window in the CacheKey property (in this case it is Calendar1.SelectedDate).
  • To enable time-based caching, type in the desirable number of seconds in the Duration property ,  or
  • To disable time-based caching and use only custom caching set the Duration property to "-1."
  • Type the name of the Boolean variable that will be used to invalidate the cache in the property InvalidationVariable" (in this case it is sp500Invalid).

    		•

    Define three property of Data Packet control.

    Define three properties of Data Packet control.

    Step 2: Define a custom invalidation rule.

  • In the Page class declare the Boolean Invalidation Variable used in the previous step.
  • Write code that sets the Invalidation Variable to True when you need to invalidate the cache according to your business rules.

    • Note 1: Server code can access the age of the cached data using the API call GetPacketLastModified().

    Note 2: The Web Stimulus API fully supports IntelliSense.
