Caches_action does not go off the entire URL

I am trying to use caches_action and the agile book says that it is
keyed
off the URL, however it does not seem to pick up the URL parameters.

http://localhost:3000/controller/action/id?foo=bar
and
http://localhost:3000/controller/action/id?foo=foobar

Returns the same page.

Anyone looked into how to add URL parameters to the cached key? Also,
where do those file get stored?

Thanks

Yeah Rails doesn’t cache the query string. In your case its caching
http://localhost:3000/controller/action/

There’s an action cache You might want to look at this presentation
http://scottstuff.net/presentations/rails-caching on Rails Caching to
understand its weaknesses. Also look at
http://scottstuff.net/blog/articles/2006/01/20/time-limited-caching-for-rails.
Typo has code that you can grab that allows for caching based on
parameters.

done in a PC.

There is an action_cache plugin that extends the action_cache code to
allow
you to do this. There is an example of how to do this in the README.

Hi David

I have the same issue. It seems you have to use a Proc with the query
params.

Example here:
http://stackoverflow.com/questions/1988658/rails-action-caching-with-querystring-parameters

In your case you need to update params[:foo]. So a better Example is
this:
