    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.

  • cc96e5cc   HTML optimizations ... Browse File » 
    This commit introduces a lot of changes in the HTML generated by Nosfero
with the intent of making it load faster on users' browsers. This
includes:

  * Adding apache configuration for compression of text content and
    aggresive cache policy (caching assets for 1 month)
  * Drastically reducing the number of stylesheets and javascript files
    referenced in the HTML.
  * The remaining CSS and Javascript files are now cached in a single file
    (one CSS file and one Javascript file) so that clients will only
    request a single file instead of several ones (and thus requiring a
    single HTTP connection instead of several ones).
  * Making sure that all assets referenced in the code have a timestamp
    (?21083219837) in the end of the URL so that when they are updated the
    client will fetch them again.

During the course of the implemeantion, some other changes were made:

  * Updated INSTALL file with documentation about apache configuration for
    production environments.
  * Marked as deprecated all methods that use stylesheet_import, as well
    as stylesheet_import itself.
  * Removed "better browser promotion" code. It sucks.
  * Unifyed Noosfero stylesheets)
  * Unifyed stylesheets in the base theme
  * Enhanced the sample-data script with the creation of random events.
    in a range of 60 days around the current date, so that there will be
    events in the previous month, in the current month and in the next
    month.
  * Removed unused cms.js
  * Updated .gitignore example to ignore cached CSS and Javascript files.
  * Updated git-upgrade script to remove cached CSS and Javascript files.
