Hi, We are facing a few issues with the channel API. May be Moishe or others can answer with some experience can answer.
1. We pre-create the channel/token by appending the page_id to the user_id before serving the page. We memcache this token for a TTL of 2 hours. When the channel is closed, we request the token again from the server, at which point the memcache is also updated with the new token. On the page itself the javascript client uses the token to open the channel using: var channel = new goog.appengine.Channel(token); If i access the web app after several hours and access my page, this call is relatively fast (few ms). However on every subsequent request, it takes ages (several minutes) for the response. The browsers status bar shows: Waiting for talkgadget.google.com (which btw makes me think that the underlying technology under the channel api is google talk, xmpp) Even if i refresh the page immediately, the same thing happens (i.e. it goes in a wait state for a long time). I have also tried doing this with other apps (for example the online paint app that someone created to demonstrate channel api). My question is, if a channel has been opened by a client web page and another client webpage tries to open the same channel, what happens? There currently seems to be no way to avoid this because the user might want to navigate to some other section of the website and then come back to the page where the channel is open. 2) My second question is: Is there a way for a user to be logged on to two different browsers and receive updates from the server to the same page? I have thought of some ways of accomplishing this e.g. appending the browser properties in the request to create the token but they all sound like hacks rather than actual solutions. 3) FInally, perhaps the above scenarios are there because the api is not ready for production use? In that case should we do nothing and wait for these issues to resolve? Thanks, Yasser -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
