Django SSI

See http://wiki.nginx.org/HttpSsiModule

{% load nginxssi_tags %}
hello
{% nginxssi %}
    <b> okidoki </b> {%now "jS F Y H:i"%} Hello {{foo}}
{% endnginxssi %}
world

Renders inline as:

hello
<!--# include virtual="/nginxssi/a3e5fa678243e0bab620fbca75f6601d/" -->
world

A request to /nginxssi/a3e5fa678243e0bab620fbca75f6601d/ renders:

<b> okidoki </b> 25th January 2011 13:26 Hello bar

Nginx will stitch these two together to form:

hello
<b> okidoki </b> 25th January 2011 13:26 Hello bar
world

How it works

1. The template is cached in its raw unrendered form
2. The template string's md5 hash is used as a cache key
3. The template's context is stored with the cache key as a prefix
4. A request to the SSI url looks up the template and the context in the cache, renders it and returns the HttpResponse
