how to fix caching

Hi all,

Basically I need to turn off caching on 100%, but maybe something else will help.

I have a next problem -

in main layout: <% if current_user and current_user != :false %>   <!-- html for logged in user, Hi user... --> <% else %>   <!-- html for not logged in user, Login please... --> <% end %>

if I login all works fine, I see "Hi user", but when I press logout link, page redirected to "/", and I see same "Hi user" text. (when I reload page with ctrl+F5 page reloaded to valid, with "login please" text) Server returns 304, but how this can possible? page must be with other content.

I use next tags in layout - <meta http-equiv="Pragma" content="no-cache"> <meta http-equiv="Expires" content="-1"> <meta http-equiv="CACHE-CONTROL" content="no-cache">

and put next cofig into the \config\environments\ - config.cache_classes = false config.action_controller.perform_caching = false

I see this bug in WEBrick (dev) and in Mongrel (production), with same configs and templates.

How I can say to browser always reload a html? or to ROR - not use 304 status, always re-render html?

He, found a method to fix this: in application.rb -

  before_filter .... , :set_header

protected   def set_header     # set modify date to current timestamp     response.headers["Last-Modified"] = CGI::rfc1123_date(Time.now - 1000)     # set expiry to back in the past     # (makes us a bad candidate for caching)     response.headers["Expires"] = 0     # HTTP 1.0 (disable caching)     response.headers["Pragma"] = "no-cache"     # HTTP 1.1 (disable caching of any kind)     # HTTP 1.1 'pre-check=0, post-check=0' (IE specific)     response.headers["Cache-Control"] = "no-cache, no-store, must-revalidate, pre-check=0, post-check=0"   end

Good in IE and FF, but sometimes not helps in Opera.
