Hi Mo,

one note, we recently removed SimplePush from our Openshift Push cartridge, but more inline

Hi,

We use  OpenShift AeroGear Push Server Cartridge
<https://github.com/aerogear/openshift-origin-cartridge-aerogear-push>  .

I've decided to register with simple-push and unified-push every time the
user logs into our application.  Also to unregister from both unified-push
and simple-push when they log out or browser closes.  Is this a good idea or
bad idea?
Any reasons you are doing it this way ? AeroGear's SPS  JS implementation will keep a mapping SPS <-> UPS in your localStorage, so when you register again it will use this instead of creating a new installation.

Sebi, Is that really the case? is it really stored? and a reconnect works?

One big issue w/ SimplePush is, there is no notion of getting an ACK about if the channel is gone or not.
Our server returns 200 for each PUT:
https://wiki.mozilla.org/WebAPI/SimplePush/Protocol

However, I recently noticed, that (regardless of the SimplePush Spec), the deployed MOZ server (wss://push.services.mozilla.com)  has a different notion:
200 -> OK (channel is active/registered/online)
202 -> Accept (chanel is known, but not yet online - scheduled for later delivery)
401/405 -> "errors" IMO sent when the PUT URL is invalid

I think perhaps we need to revisit this in our Server impl.


By registering/unregistering each time you will "pollute" the installation table in UPS.

unregister will enure bogus installations (w/ eventually outdated channels) are no longer in the DB.

simplepush is a bit different here - yes :-)
 


Also, I've always wondered about the following comment in a sample code:

"if it is the first registration, need to register the 'pushEndpoint' with
the UnifiedPush server."
<https://github.com/aerogear/aerogear-js-cookbook/blob/master/simplepush-unifiedpush-example/js/unifiedpush.js#L27-L28>
Once a SPS endpoint has been received it needs to register with the UPS except when it has already be done (see previous comment) 

Can somebody explain what is meant by the comment?  For example, what would
count as a registration that's not the first?

Thank you.
