1df72533 First stab at HTTP caching ... Browse Code »

Implemented cache policy:

  * the homepage is cached for 5 minutes by default. This time can be
    configured with the =home_cache_in_minutes= attribute in the environment.
  * non-profile pages are cached for 15 minutes by default. This time can be
    configured with the =general_cache_in_minutes= attribute in the
    environment.
  * profile pages are cached for 15 minutes by default. This time can be
    configured in the =profile_cache_in_minutes= attribute in the environment.
  * The account controller (/account/*) is not cached at all.
  * The environment administration area (/admin/*) is not cached at all.
  * The profile administration area (/myprofile/*) is not cached at all.
  * Since Varnish will not cache any request that involves cookies:
    * Authenticated users will not benefit from the cache.
    * Cookies are not allowed for unauthenticated users. So, when a response is
      being prepared for an unauthenticated user, all cookies are wiped out.

The contents of the login block and the login/logout part of the header is now
loaded via an AJAX call to /account/user_data. This way we can cache almost all
pages without caching user-specific data.

We are also changing substantially how the flash[:notice] messages work. From
now on, instead of setting flash[:notice], we must set session[:flash]. It will
work more or less like before, except that session[:notice] will be consumed by
the AJAX call to /account/user_data that is done during all page loads instead
of being consumed automatically by Rails. The only exception to this is the
media_panel, because it uses a different layout.
