This middleware provides the inverse of the Django CommonMiddleware APPEND_SLASH feature. It can automatically remove trailing URL slashes and 301 redirect to the non-slash-terminated URL. This behavior is performed if the initial URL ends in a slash and is invalid, removing the trailing slash produces a valid URL, and REMOVE_SLASH is set to True. Otherwise there is no effect.

For example, foo.com/bar/ will be redirected to foo.com/bar if you don't have a valid URL pattern for foo.com/bar/ but do have a valid pattern for foo.com/bar and REMOVE_SLASH=True.

To install django-unslashed,

pip install django-unslashed

If you're using a requirements.txt file, add django-unslashed>=0.3.0 to it.

Modify your Django settings.py file to add unslashed.middleware.RemoveSlashMiddleware to your MIDDLEWARE_CLASSES just before or after django.middleware.common.CommonMiddleware.

MIDDLEWARE_CLASSES = (
    # ...
    'unslashed.middleware.RemoveSlashMiddleware',
    'django.middleware.common.CommonMiddleware',
    # ...
)

Set REMOVE_SLASH to True and APPEND_SLASH to False,

APPEND_SLASH = False
REMOVE_SLASH = True

If REMOVE_SLASH is False or unset, the RemoveSlashMiddleware has no effect.

Web applications should have a URL structure which either:

1. Uses trailing slashes and redirects to append slashes if invalid non-slashed-terminated URLs are accessed.
2. Uses no trailing slash URLs and redirects to unslahed URLs if invalid slash terminated URLs are accessed. The prior is the Django default, while the later is possible by adding this middleware to your project.

Based closely on Django's APPEND_SLASH CommonMiddleware implementation.
