HTTPS redirections middleware with updated URL template tag

This middleware redirects HTTP requests to HTTPS for some specified URLs, in the same way as [85](http://djangosnippets.org/snippets/85/). It also changes the `url` template tag to use the `https` scheme for the same URLs. For example, if you have the following URL pattern: url(r'^accounts/login/$', 'django.contrib.auth.views.login', {'https': True}) then the template: {% from future import url %} {% url 'django.contrib.auth.views.login' %} will render: https://host.example.com/accounts/login/ and any plain HTTP requests to /accounts/login get redirected to HTTPS. URL patterns not marked with `'https': True` remain unaffected. Notes: * The HttpRequest object must be present in the template context as `request`, so add `django.core.context_processors.request` to `TEMPLATE_CONTEXT_PROCESSORS` and make sure to use `RequestContext`. * This snippet overrides the existing `url` template tag. Remove the last line and register the new `url` function properly, as a separate tag, if this makes you unhappy. You'd then have to change your templates to use it. * It would be nicer to change the way reverse look-ups behave instead of changing only the `url` template tag, but the URL resolver, and the `reverse` function, know nothing about requests, so have no way to find the correct host name.

Amazon S3 browser-based upload form(FIXED)

This is a 'fixed' version of snippet [1868](http://djangosnippets.org/snippets/1868/) Changes: *Correctly handle the Content-Type, because amazon requieres it to be named with a dash and we can't use dashes in the form attributes declaration. *Also added max_size handling, with the corresponding update to the policy generation. *Added an example usage with some javascript for basic validation. [See the amazon reference](http://aws.amazon.com/articles/1434?_encoding=UTF8&jiveRedirect=1)

Filter to add zero-width space to break up long words

If you have long words (no spaces) that are so long that it's messing up your design, add a 0-width space in the word every X chars. Usage: Step 1. Inside your app's directory, create dir called 'templatetags'. In that directory, create a .py file (say 'app_extras.py'). Make sure you make this a python module, make an empty the init .py (with the 2 underscores on each side). Step 2. Inside template (make sure app is on INSTALLED_APPS list in settings.py): {% load app_extras %} Step 3. Enjoy! {{ some_long_word_with_no_breaks|zerowidthspace_separator:25 }}
