Can I control what caches are flushed via "Flush all caches"? I use the module Boost and anytime I click "Flush all caches" it deletes all the cached pages already built. Is there any way to make "Flush all caches" to flush all cache instead of the Boost-created .html.gz cached pages?
If you're using the admin menu module you can selectively target which cache to flush by hovering over the the Flush all cache menu under the home icon. The Class registry and Page and else will wipe out the Boost cache, but everything else will leave it intact.
