#34028: Django 'static' template tag fails to generate URLs with SCRIPT_NAME
prefix

-------------------------------------------+------------------------
According to the docs, when MEDIA_URL and STATIC_URL are relative (now the
default), SCRIPT_NAME should automatically be prepended to them when it is
set to ensure that paths are generated correctly. This appears to work
everywhere *except* when calling `{% static %}` in HTML templates.
Best I can tell, when this functionality was first added, it appears that
SCRIPT_NAME was evaluated every request:
https://github.com/django/django/commit/c574bec0929cd2527268c96a492d25223a9fd576
Looking at this same file today, it appears that setting values are now
cached in a dict. When the Django application initializes, it reads
SCRIPT_NAME as / and so all subsequent uses of `{% static %}` are output
without the current value of SCRIPT_NAME. This happens even if using a
hardcoded FORCE_SCRIPT_NAME.
url() appears to be unaffected by the same issue, so the net result is
that links and redirects honor SCRIPT_NAME as expected, and static files
are served using the SCRIPT_NAME prefix, but all output from HTML
templates simply use `/static/...` for their links which causes all
css/js/favicon/related media to fail to load with a 404.
