Initial situation: Inside a function I'm caching a query using the cachedWithin attribute. Right below that cfquery tag I'm caching derived&related data into a struct stored in the SERVER scope.

Problem: I want to re-populate that struct if the query above has been refreshed, but foo.cached only seems to indicate whether the tag uses caching at all. Does Railo provide additional metadata to actually receive true if that query has been updated, not just if it's cached at all or should I resort to a cfcache workaround?

I believe that result.cached is what you need. I've just tested sample query with small cachedWithin time span and it was set to false in two cases: (1) when records added; (2) when timeout happened. So your first guess looks OK.

  • Strange. I tested it using 3.2 and "cached" was always set to true. Hence that post above. Can't try 3.3 at the moment, since some of the legacy code in that application would need to be made compatible first (good thing the Railo server admin has a rollback feature). – mz_01 Nov 02 '11 at 20:54

Just in case anyone's interested:

Since the "cached" attribute didn't turn out to be reliable in my case (might be because I inherited this system from my predecessor and can't vouch for how much of the application server has been modified in the past) I resorted to a different approach, based on the classic cacheGet/cachePut block.

The resulting caching decision logic is based on the timeout of the subsequent struct that's fed by this query.
