From the post:

> As TabSub uses local store this only works on the same domain, as the browser separates the local storage by domains as security measure.

(More precisely, the separation is based on origin, which is roughly the combination of protocol, hostname, and port.)

The conclusion is this only works between tabs that have the same website open.

But it's offline, what's the website? Or offline doesn't mean offline?

    I think in their case, offline is as in you don't need to set up a pubsub server and the client doesn't have to talk to a server for the specific pubsub functionality, not as in "use this for offline web pages/html files locally" (it may or may not work for that, I have no idea, didn't look).

      Works for offline apps as well :) (you would need to download the tabsub JS ofc and not use it from my server)

    It means, that you don't need an internet connection for this to work :) (so it is no rabbitmq or so which runs on a server and the browser is just the client)

    You can try on the demopage when you

    1. play the songs each (for them to buffer a little audio snippet)

    2. open the page in a second tab

    3. Disconnect from the internt

    Still works :D

      I'm just asking random questions now and then to get an idea of how things work in the web world. Especially those that aren't mentioned in tutorials.
