The path parameter specifies a document location for the cookie, so it’s assigned to a specific path, and sent to the server only if the path matches the current document location, or a parent:

document.cookie = 'name=Flavio; path=/dashboard'

this cookie is sent on /dashboard, /dashboard/today and other sub-urls of /dashboard/, but not on /posts for example.

If you don’t set a path, it defaults to the current document location. This means that to apply a global cookie from an inner page, you need to specify path=/.
