Jinja2 extension that adds support for caching template fragments.
Usage:
{% cache timeout key1[, [key2, ...]] %}
...
{% endcache %}
By default the value of "path to template file" + "block start line" is used as cache key.
Also key name can be set manually. Keys are concated together into a single string.
that can be used to avoid the same block evaluating in different templates.
Set timeout to "del" to delete cached value:
{% cache 'del' key1 %}...
Example:
Considering we have render_form_field and render_submit macros.
{% cache 60*5 'myform' %}
{% endcache %}
