Background workers

window.host

Background workers are invisible browsers (without a user interface).

Their behavior is similar to docking widgets: their state is saved across sessions when in normal mode and they are disposed of when state switches to on-boarding mode.

The background worker HTML code is supplied directly when adding a new worker and not loaded from a remote server. This allows the background worker to be self-contained and independent of Internet connection availability and quality.

The URL supplied as part of the background worker initialization is used to determine the security context (i.e. accessible cookies, CORS origin, etc.) of the background worker browser.
