Base Tornado handlers for the notebook.
RequestHandler with default variable setting.
A RequestHandler with an authenticated user.
Is a user currently logged in?
May a user proceed to log in?
This returns True if login capability is available, irrespective of whether the user is already logged in or not.
IPython-specific extensions to authenticated handling
Mostly property shortcuts to IPython-specific settings.
Return the jinja template object for a given name
use the IPython log by default, falling back on tornado’s logger
Use less instead of css in templates
websocket url matching the current request
By default, this is just ‘’, indicating that it should match the same host, protocol, port, etc.
Bases: IPython.html.base.handlers.IPythonHandler, tornado.web.StaticFileHandler
static files should only be accessible when logged in
subclass of StaticFileHandler for serving files from a search path
Generate the version string to be used in static URLs.
This method may be overridden in subclasses (but note that it is a class method rather than a static method). The default implementation uses a hash of the file’s contents.
settings is the Application.settings dictionary and path is the relative location of the requested asset on the filesystem. The returned value should be a string, or None if no version could be determined.
locate a file to serve on our static file search path
Converts a static URL path into a filesystem path.
url_path is the path component of the URL with static_url_prefix removed. The return value should be filesystem path relative to static_path.
