As i said ive only imagined such a feature. In my imagination i wonder if it is possible to track the clients address in a data structure within the application. Then a connection could be established whenever a push was needed. I also think the app would have to track the last page a user requested in order to realize such an implementation. This *should* be feasible using sessions because whenever the client makes a new request the last page variable could be updated. I havent seen nor heard of Comet; would you mind providing a link? -nathan On 7/13/07, Robert Cummings <robert@xxxxxxxxxxxxx> wrote:

I haven't looked at the code for Xaja and in no way do I want to subtract from its potential, but I'm going to guess that in some way it holds the HTTP connection open and as such is an expensive feature. Also, I'm not entirely sure, but isn't that the principle that Comet uses? Cheers, Rob. -- ...........................................................
