I'm using views caching after reading this great Q&A and getting good results. I have to keep the expiration short because I'm showing the "last comment" in the view and those changes often.
What I would like to do is rebuild the cache immediately after it expires? I read that boost module offers that but I need a solution for authenticated visitors (already use Varnish for anonymous).
The cache graceful module seems to offer that but only has 20 installs (plus requires a couple of other modules).
Are there any other solutions that allow expiring a cache and "warming" it up right away?
