armstrong.esi
=============
Django application for handling `edge side include (ESI)`_
.. _edge side include (ESI): http://en.wikipedia.org/wiki/Edge_Side_Includes
Usage
-----
ESI allows you to specify sections of the site that require different caching
strategies and can be sent to a smart caching layer for rendering.
For example, if you want to send a page that is identical for every user except
for a welcome message, you could render that message like::
<html>
<body>
<esi:include "/esi/welcome-message" />
... the rest of the page ...
</body>
</html>
A smart proxy such as `Varnish`_ and the middleware included with
``armstrong.esi`` can cache this page, and send a request for /esi/welcome-message
for personalization. The next user hitting the page would get the cached version and
your application server would only need to render /esi/welcome-message
armstrong.esi provides a template tag for rendering the correct urls with the same
syntax as django's url tag. For example, the above example becomes::
{% load esi %}
<html>
<body>
{% esi welcome_message %}
... the rest of the page ...
</body>
</html>
This replaces our ``{% esi %}`` tag with a ``<esi:include>`` tag pointing to
the URL for that view.
.. _Varnish: http://www.varnish-cache.org/
Using with Varnish
""""""""""""""""""
`Varnish`_ integrates fairly easily with armstrong.esi. The EsiHeaderMiddleware
sets the 'X-ESI' header to 'true' if the page request has esi tags on it. To
enable esi processing in varnish for pages that need it, add the following to
your vcl_fetch method::
if (beresp.http.X-ESI) {
set beresp.do_esi = true;
}
Loading without ESI
"""""""""""""""""""
The template tag reads the ``DEBUG`` settings value and if set to ``True``
renders the view with the current request rather than including the
``<esi:include>`` tag. This makes it easy to see fully rendered pages in development.
Installation & Configuration
----------------------------
You can install the latest release of ``armstrong.esi`` using `pip`_:
::
pip install armstrong.apps.articles
Make sure to add ``armstrong.esi`` to your ``INSTALLED_APPS``. You can
add this however you like. This works as a copy-and-paste solution:
::
INSTALLED_APPS += ["armstrong.esi"]
You must also enable the armstrong.esi middleware. To do this, add the following
line to your ``MIDDLEWARE_CLASSES``::
'armstrong.esi.middleware.EsiMiddleware'
.. _pip: http://www.pip-installer.org/

State of Project
----------------
Armstrong is an open-source news platform that is freely available to any
organization. It is the result of a collaboration between the `Texas Tribune`_
and `Bay Citizen`_, and a grant from the `John S. and James L. Knight
Foundation`_. The first release is scheduled for June, 2011.
To follow development, be sure to join the `Google Group`_.
``armstrong.apps.articles`` is part of the `Armstrong`_ project. You're
probably looking for that.
