I recently ran across CFOBJECTCACHE, which has a single attribute with a single option, action="clear". This was introduced in CF5.
I haven't used it, yet, but it looks like I might have a reason to, soon. But I am wondering if Adobe (or even Lucee) is planning on modifying it so that one can clear a specific query (as opposed to all cached queries within an application)? Seems to me that if one has a site/app that has many (say, 30 or more) cached queries that this could put a huge strain on the CF Server due to all queries being re-run after this tag is used.
I know that this isn't a forum that is staffed by Adobe employees, but occasionally an Adobe employee does peruse, here. What say you, Adobe?
