[Laszlo-user] Sending dataset over HTTP

[Peter Brand]

... to be (more) precise: I switch from LZX to XHTML just when it comes to
data transfer from applications (comprising embedded LZX) to data sources.
In many other cases I extensively use LZX; it's great pleasure (as you may
have seen from my website www.eines-alles-nicht.org or from the following
small application for my grandchild:
http://www.eines-alles-nichts.org/Niels/Spiel.html). 

Regards

OK, but I really need LZX, XHTML is not equivalent and I need the power of
LZX for the end user experience.
