Hello everybody,
does anybody know if the "canonical id" mechanism, which is described in the GCM-over-HTTP documentation, also exists in the CCS (XMPP) protocol??
My first guess would be, that the "from" value in the ACK message does the job of "canoncial id", but it's not documented anywehere :-(
On the other hand, the "from" value is always present in the ACK message, whereas the "registration_id" in GCM-over-HTTP is only present in the response, if there is a canonical id.
I couldn't test it, because since Google approved my account for using CCS (XMPP), I couldn't enforce a registration id change....
Can somebody confirm my guess? Or how do you handle the "canonical id" problem at CCS (XMPP)?
Regards,
Sebastian
