I don't believe that prototype supports persisted xmlhttp connections. 

If you are interested in alternatives, dojo does support it.

Hi,

A cool _javascript_ programming techniques is used in GoogleTalk and
Google Spreadsheet.
They leave opened an XmlHttpRequest to send and receive data. That's
why they are so reactive. It works because there's no navigation
(request) only ajax.

My questions are:

1. Does prototype allow that kind of long ajax request ?

2. Is it possible to store _javascript_ Object in the scope of the navigator ?
-> Firefox allow storing vars in object "Navigator". But not IE. The
vars are available during single tab navigation. But I don't know if
XmlHttpRequest stay opened ?


Best Regards,
Jp
