Do web workers terminate when the user navigates to a new page (within the same application)

Question

For example, can i offload a task and allow the user to keep surfing my site whilst the javascript runs?

It seems if I navigate away from the page, the worker terminates.

Answer 1

A "page navigation" in the browser means that everything that used to exist (HTML, CSS, JavaScript, plugins, etc.) cease to exist, and the new page is loaded as if you had opened a new browser window. Web workers make more sense in the context of a "web application" than a "web page". If you are writing an application that lives in the browser, consider ditching the "page" metaphor and construct a UI that doesn't need to navigate the browser every time you change context.
