asp.net app still using old data after SSIS Package updates it

I have got a SSIS Package running every 2 hours. It collects data from different DBs 开发者_如何学Goand updates the DB of my ASP.Net Application. Everything goes smooth, but the asp.net application is still using the old data, it has the data somehow cached. If I just open save the web.config, it empties the cache and uses the updated new data. How can I make sure, that the app empties the cache after SSIS Package finished successfully?

If this is your code then you should use SqlCacheDependency. If not then you can add special aspx page and call it from SSIS. This page can refresh cached data.
