Time-based cache fragment expiration

Rails
1

Hello,

I’m trying to figure out how I could implement fragment caching that
expires every x amount of time. I thought of writing a runner script
that would expire the cache and set it as a cron job, but that
doesn’t really work because runner scripts act on models and not
controllers.

Does anybody have any ideas?

I was hoping someone would jump in here with the solution. I had the
same
problem and couldn’t figure it out. I ended up just using a cron job to
delete them.

I believe the Typo project has done what you need. Take a look at
http://www.typosphere.org/trac/browser/trunk/vendor/plugins/expiring_action_cache/lib/metafragment.rb

I’ve been meaning to implement this, but its low on my priority list.

cheers,

I haven’t done extensive testing, but we use memcache to store
sessions/fragments and with some minor tweaks you can pass along an
expiration time (ie. expire automatically in 10 minutes)…

The automatic expiration is a part of memcache… if you’re interested
let
me know and I’ll write it up.

I’ve done it with using MemCached as a cache backend and described it
here:
