`HttpRequest.scheme` is `https` if `settings.SECURE_PROXY_SSL_HEADER` is appropriately set and falls back to `HttpRequest._get_scheme()` (a hook for subclasses to implement) otherwise. `WSGIRequest._get_scheme()` makes use of the `wsgi.url_scheme` WSGI environ variable to determine the request scheme. `HttpRequest.is_secure()` simply checks if `HttpRequest.scheme` is `https`. This provides a way to check the current scheme in templates, for example. It also allows us to deal with other schemes. Thanks nslater for the suggestion.
The documentation in this tree is in plain text files and can be viewed using any text file viewer. It uses ReST (reStructuredText) [1], and the Sphinx documentation system [2]. This allows it to be built into other forms for easier viewing and browsing. To create an HTML version of the docs: * Install Sphinx (using ``sudo pip install Sphinx`` or some other method) * In this docs/ directory, type ``make html`` (or ``make.bat html`` on Windows) at a shell prompt. The documentation in _build/html/index.html can then be viewed in a web browser. [1] http://docutils.sourceforge.net/rst.html [2] http://sphinx-doc.org/
