This is pretty much how FlashConnect was designed to operate. The
FlashConnect executable, referenced in the URL, resides on the web server
while the D3 component, an account on the dbms server, creates a socket
connection to the web server. The D3 server can be anywhere, and usually
is.
The URL references the FC executable and also identifies the D3 program to
run (and on which account). The D3 program usually reads in the form data,
does some processing, builds a return web page, using templates or whatever,
then returns it back to the FC executable, which sends it back to the
browser.
U2s RedBack product does pretty much the same thing. It has some additional
IDE components and the you're charged for the U2 account (the server)
component. This makes the U2 solution significantly more expensive and not
likely to be used for expanding an mvDbms developers market, but then not
too many people are using D3 and FlashConnect either.
This explains why it's difficult for mvDbms developers to get out into new
markets and develop new solutions; because the mvDbms suppliers are killing
us with high costs.
