I enabled channel presence in google app engine, so I get a “ping” whenever a client connects/disconnects a channel. This is great! However, it’s not enough. I would like additional information. For example: which page the client is on (i.e., the uri the client sees), or additional JS variables.
I didn’t find any mention of this on google’s tutorials. How do I do this, and is it even possible?
Thanks!
It’s not possible for technical reasons — the server generating those requests has no knowledge of the state of the client. If you want that data for connect, though, you could manually POST (to a different URL) when you get the onopen callback.
