right and the URI, returned to the 'user agent' can be stored
on your
'application', like UPS.
No. The WebLink URL of type "push:channel" returned from the registration
request is not shared. When an application requests a channel, the device
uses the "push:channel" URL to create a new channel for the application.
This channel creation request will contain a "Location" header with the URL
that the application will share with a backend, enabling it to send
notifications.
I wonder why I (being a device/user-agent) explicitly have to create
that
channel.
I think the spec needs to cater for the ability to have a single web
browser case where there a service worker serves multiple applications. For
a mobil device it might not make sense to have this shared, and in this
case the API can hide the registration. From the end users point of view it
could be seen as only a register, something like:
http://w3c.github.io/push-api/#example
Not sure, but I think it might be useful to have an unmonitor, to
quite
the abo of some content, e.g. at some point #Rihanna might get boring :-)
If that is the case then I think you can delete the channel. Since the
"device" is not specific to a single applications (it could be serving
multiple) it still need to be monitoring to receive notifications for other
channels.
Or am I having a misunderstanding of the concept here ?
Well if
you are, then it is me doing a bad job at explaining/describing
things. I should say that I'm still learning and might not have correct
answers for things yet.

ok, I see that a few extra 'creates' are needed, for multiple channels.
But what's the use case of a register without creating a channel? Just
simply to monitor on an existing or different channel ?

Well, sue I can still 'ignore' it in my code of the service-worker, but
would be nice if that guy was no longer bothered :)
