Clearing memcache without restart

Up until now, I always restarted memcache to clear it. However, you can make a rake task to do so:

1 namespace :cache do
2   desc 'Clear memcache'
3   task :clear => :environment do
4     ActionController::Base.cache_store.clear
5   end
6 end

Drop this into /lib/tasks/cache.rake. Now just run the task:

1 rake cache:clear

This only works if you have configured action_controller.cache_store to be memcache.

Have a good weekend!
