I''m just getting my hands dirty with caching. The pages I want to cache have some user specific data on them (for example "log out"). That sent me down the route of fragment caching. One of the things I want to pagination is a paginated list. My question is how is pagination and query strings handled with fragment caching? Does each page get its own fragment and query string identifier? thanks, Steve http://www.smarkets.net -------------- next part -------------- An HTML attachment was scrubbed...

Yes. Each page related fragment is cached separately.
Here is what works for me:
In the view: (event/list.rhtml, a paginated view, with an optional
''year'' filter. )
line 1: <% cache(:controller => ''event'', :action
=> ''list'', :group
=> visitor.group, :page => params[:page], :year => params[:year])
do%>
...
In the Controller:
class EventController < ApplicationController
cache_sweeper :event_sweeper, :only => [:edit, :update, :new,
:create, :destroy]
...
In the sweeper:
class EventSweeper < ActionController::Caching::BaseSweeper
observe Event
def after_save(record)
expire_fragment %r{event/list.*}
expire_home_page
end
def after_destroy(record)
expire_fragment %r{event/list.*}
expire_home_page
end
end
Excellent. Just what I was looking for.
