Does Caching in ColdFusion returns the updated data and Cache again?

Question

No code required.. Just asking. (Please bear with me, English is not my primary language)

Here is the scenario.

I cache a query for 2 hours, and the data is updated in the database before 2 hours are completed. So my question is will the new data from the database will be included in the cache?

Answer 1

The answer is NO. If you specify your cache timeout this is what it will be. It will NOT even check the database for the timeout duration.

Generally, you should NOT use cachedWithin if your data is likely to change because this attribute tells CF to use cached data without checking database. If you used cachedWithin and you somehow found out that the data has changed you have no easy way of forcing re-query
