Use a cron job. Look at the last modified dates of the files.

in php::pear simplecache I could define an expiration date for each
cache
fiel that I create. So that I didnt violate DRY. If I create cache
somewhere
but check for it elsewhere I kind of repeat my self.

Isn’t it more dry to use the OS to find and remove old files?
At any rate, write a plugin or something to do what you want. I’m
guessing no one’s really needed the feature bad enough to implement
it.
For example my latest comments fragment must be expired in 5 minutes.
But my
tagcloud must be expired in 1 day. If i code this one by one into a cron
job, that’ll be unmaintainable.
my solution is holding all my caches in database (id, cache_file_name,
expire_at) and run a cron job that calls the ubry script that checks
this
table and expires fragments when necessary.

The easiest way is to use a cron job to either run a script with
script/runner that will expire the cached pages. Or you can just have
the cron job erase the cached pages in your public directory,

Nah… how is it any less maintainable than doing it any other
way??? I say don’t make things complicated.
man find
look at -[acm]time OR -[acm]min, and -delete
oh, and BE CAREFUL (i.e. test with -print before using -delete).

I just wrote this plugin today for something else, but it may work for
you too:
http://techno-weenie.net/svn/projects/plugins/referenced_page_caching/
Referenced Page Caching is a small wrapper around Rails’ page caching.
It allows you to add references to a current page’s cache file.
These references are then used to expire all the pages that are
referenced when it is modified or destroyed.

whenever I create a new cache type, I will have to go to the cron job
and
add a sweeping action for it including its expiry time (as every file
can
have different lifetimes). I think its much more maintainable when you
specify the expiry time wherever you define the cache.
Maybe, this is what you are looking for:

Hello railers
I’m also trying to delete some caching every hour.
I’ve set a cron job for executing every hour
/home/www/script/runner ‘ActionController::Caching::Pages.expire_page(
:controller => “home”, :action => “index” )’ -e production
but it raises an error:
/usr/local/lib/ruby/gems/1.8/gems/rails-1.1.1/lib/commands/runner.rb:27:
undefined method `expire_page’ for
ActionController::Caching::Pages:Module (NoMethodError)
Any idea ?
Thanks
