Django custom templatetag not getting request in context

I am using django 1.4 and trying to convert the code described at the end of this article to customtag. This means that I need access to the is_secure and site_name values ​​from the request. Here are my CONTEXT_PROCESSORS in settings.py:

CONTEXT_PROCESSORS = (
    'django.core.context_processors.request',
    'django.contrib.auth.context_processors.auth',
)

Here is my template tag code:

from django import template
register = template.Library()

@register.simple_tag(takes_context=True)
def full_static_url(context, url):
    request = context['request']
    scheme = 'http'
    if request.is_secure:
        scheme += 's'
    return scheme + '://' + request.site_name + context['STATIC_URL'] + url

In my view code, I use the new render shortcut like this:

return render(request, 'myapp/mytemplate.html', {'foo':bar})

And I call it like this in the template:

{% full_static_url "images/logo.gif" %}

The problem is that when it falls into the request = context ['request'] line , it throws a KeyError because the “request” is not in context.

What am I doing wrong here?
