Rails - Feb 2006 - 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

Dave

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.

The only way I got it to cache parameters is by using fragement caching.

<% cache :controller => ''search'', :action =>
''results'', :id => ''1'', :param1
=> ''p1'', :param2 => ''p2'' %>

code........... html...........

<% end %>

If you use file store for fragment caching, you can define the cache
location.

Hope this helps,
Mac

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.
