The client is polling the server for new data that could come up
because of external events.
If I understand correctly, this kind of application is useful for a
certain class of websites like chat, real time data updating (like
stock quotes), etc..
In majority of ajax applications, such polling might be useless isn't
it?
Not quite useless. The reason I originally wrote AjaxPage was for a
system that can have long-running requests to the server (generating
reports). In that case, I was fighting against browser/server
timeouts. On our installation of Apache, the client/server connection
would be broken after 5 minutes.
OK!!!
This is a VERY specific application.
I thought the ajax page was a base class for any ajax application but it
is absolutely not...
Believe me that a vast majority of http or ajax request is responded
immediately, and such mechanism is simply not needed.
Sorry for having bothered you.
