<h1>Static content</h1>
<p>Some content on a website does not change and therefore should be served
up either directly through the web server or a content delivery network (CDN).
Examples include JavaScript, image, and CSS files.</p>
<h2>Types of static content</h2>
<p>Static content can be either assets created as part of your development
process such as images on your landing page or user-generated content. The
Django framework calls these two categories <em>assets</em> and <em>media</em>.</p>
<h2>Content delivery networks</h2>
<p>A content delivery network (CDN) is a third party that stores and serves
static files. <a href="http://aws.amazon.com/cloudfront/">Amazon CloudFront</a>,
<a href="http://www.akamai.com/">Akamai</a>, and
<a href="http://www.rackspace.com/cloud/public/files/">Rackspace Cloud Files</a>
are examples of CDNs. The purpose of a CDN is to remove the load of static
file requests from web servers that are handling dynamic web content. For
example, if you have an nginx server that handles both static files and
acts as a front for a Green Unicorn WSGI server on a 512 megabyte
virtual private server, the nginx server will run into resource
constraints under heavy traffic. A CDN can remove the need to serve static
assets from that nginx server so it can purely act as a pass through for
requests to the Green Unicorn WSGI server.</p>
<p>CDNs send content responses from data centers with the closest proximity to the requester.</p>
<h2>Static Content Resources</h2>

<p><a href="http://django-storages.readthedocs.org/en/latest/">django-storages</a> is

Amazon S3 and other content delivery networks.</p>

<li>
<p>RevSys has a nice article on a range of
<a href="http://www.revsys.com/12days/front-end-performance/">important static file optimizations</a>
such as setting cache headers, optimizing JavaScript and reducing the
size of images.</p>
</li>
</ul>
<h2>Static content learning checklist</h2>
<p><i class="fa fa-check-square-o"></i>
Identify a content delivery network to offload serving static content files
from your local web server. I recommend using Amazon S3 with CloudFront as
it's easy to set up and will scale to high bandwidth demands.</p>
<p><i class="fa fa-check-square-o"></i>
Update your web application deployment process so updated static files are
uploaded to the CDN. </p>
<p><i class="fa fa-check-square-o"></i>
Move static content serving from the www subdomain to a static (or similarly
named) subdomain so browsers will load static content in parallel to www
HTTP requests.</p>
