Default: False

Set the Access-Control-Allow-Credentials: true header

Set the Access-Control-Allow-Origin header

Use ‘*’ to allow any origin to access your server.

Takes precedence over allow_origin_pat.

NotebookApp.allow_origin_pat : Unicode

Default: ''

Use a regular expression for the Access-Control-Allow-Origin header

Requests from an origin matching the expression will get replies with:

Access-Control-Allow-Origin: origin

where origin is the origin of the request.

Ignored if allow_origin is set.

NotebookApp.base_project_url : Unicode

DEPRECATED use base_url

NotebookApp.base_url : Unicode

Default: '/'

The base URL for the notebook server.

Leading and trailing slashes can be omitted, and will automatically be added.

NotebookApp.browser : Unicode

Default: ''

Specify what command to use to invoke a web browser when opening the notebook. If not specified, the default browser will be determined by the webbrowser standard library module, which allows setting of the BROWSER environment variable to override it.
