Until now i've been developing flex applications with .net as
the backend ,using HTTPSERVICES or WEBSERVICES but now i need to
use authentication on one application and to do that consistently i
read i must use a gateway like Flash Remoting.
Since Flash Remoting and Flex Data Services or LiveCycle as
it called now, are paid i searched for a free framework and i've
found this 3 to be the best ones, so my question is, does anyone
konws this frameworks in a way that can tell me the main
differences between them?
As far as I am aware Cairngorn is a framework for building
RIAs with Flex in a best practice way; and I don't believe it would
help at all with what you are asking.
In order to use authentication from .Net back-end via
Remoting there are two options that you have already identified.
Fluorine is open source and free. WebOrb would be my preferred
choice, however if you want windows authentication then you can't
use the free version and so have to pay for it (I would suggest you
email Mark Piller to confirm this though see
Assuming you have the budget to pay for WebOrb that would be my
choice - it wins out on features, maturity of the product, support
and documentation. If however you just want the basics and are
willing to figure things out by yourself and do not want to pay a
dime then fluorine looks like it will do the trick. Regarding,
LiveCycle I think that is JAVA only and so is not an option.
