- preliminary Comet support added (currently only working in a multi-
threaded env.)
Can you tell some more about this feature?
And how to use Update() in ajax components?
With best regards,
Pavel.

See http://en.wikipedia.org/wiki/Comet_%28programming%29 to know more about Comet. In a few words it allows you to push data to the user browser instead of following the classic request/response cycle. An example app is available in nagare.examples : http://www.nagare.org/trac/browser/trunk/nagare/examples/nagare/examples/chat.py
Give it a try using two browser sessions at once, you'll see :)
By the way, I was wondering how to serve Comet based apps behind Apache. I'm currently running one with mod_proxy but I have to generate fake events to prevent proxy timeout on long polling request.

Excellent! I will try it in my project :)
BTW, do you planing to release two-way comet-like interface? Now, I can easily call javascript function from nagare application, but if I want to transfer (in background) some information from browser to application I have to create hidden form, fill it from JS and emulate button-down event to do it. And it's very difficult to catch errors in this way. It seems to be easy to implement simple interface for calling python-object methods from JS (and get returned value back to JS).

May be it will be better to use specific comet-optimized web-server?
