*cough* BS.
Flash can be decompiled.
I can watch all of the traffic. Even over SSL.
I can modify AMF (I'd have to look @ secure AMF).
If you'd like to challenge me to hack the app, let me know. I'm up
for it. ;-)

This application can now act as your portal between the browser via JS
using the External Interface (or fsCommand going back to Flash ~6).
Then your "invisible" Flex/Flash app can leverage all the connection
types available (AMF/SecureAMF, Webservice, HttpService etc...) in a
manner that is not easily accessible to any hacker (you can hide all
kinds of security checks within this app).
I've always wanted to do a bench mark of this type of app side by side
with standard Ajax, but the bottom line is that the only browser
specific code would be in how the returned data is applied to effect
the client content.

Charlie, my main issues with AJAX are dealing with cross-browser

security.
AJAX exposes some of the most annoying cross-browser DHTML sort of
things.
Using libraries and frameworks can insulate you from that to a
degree, but
not always completely. I've got a customer doing things with Google
Maps and
we've had some differences between IE and FF that have been
difficult to
solve.
People have gotten so excited about using AJAX that they have
forgotten
basic security principles (things like validating input). I
recently read an
article that discussed the security holes in the more commonly used
frameworks, so the issue isn't just with roll your own AJAX, it is
more
pervasive.
But, those things said, ultimately I think it is a step forward in
making a
richer browser experience (not as much as Flex though). There are
just some
fleas on the dog that folks should be aware of in advance.

Subject: [ACFUG Discuss] will Ajax go away (was JVM version and
ColdFusion)
That seems a curious statement, Forrest, and I'm sure some would
enjoy a
bit of discussion on it. For those who weren't following closely,
he had
asked first about some challenges using a CFX_google custom tag,
and in the
replies he was told that it's quite old and instead Google favors
some Ajax
APIs instead. Forrest replies he hoped the "Ajax thing would just
go away".
So, do you realize that Ajax is merely a way to make browsers
smarter? It
enables them to make calls to remote servers. Sure, we could do
that in the
past with Java applets, ActiveX controls, Flash, and even plain
Javascript.
And we could of course do it from the server using either REST or
SOAP apis.
Ajax is just a simplified API to enable that very javascript-based
client-server interaction. For those who need to talk to servers from
clients (either because they can't or don't want to involve a
server to
proxy the communications for them), we don't want them to go back
to Java
and ActiveX, do we? :-) And while we may wish everyone would use
Flex, it's
just not likely. Many will, for the much larger problem space it
solves, but
for the average web developer, it's not really as simple as
dropping in some
AJAX API calls.
If Google (or other vendors) want to create a way for people to
connect, and
they want to make it work regardless of what web app server
platform people
use (and as well for those who have no server), and they provide an
Ajax-based API to what (I suppose are otherwise REST-based)
services, that's
seems to be just being smart, widening the pool of possible users.
Look at it another way (for us CFers), they (like Amazon, Ebay, and
others)
could instead just document calling from Java, ASP.NET, and PHP.
They tend
to not go that one step further to include CF. At least by their
offering a
platform-agnostic solution that doesn't require any server-side
processing,
they've helped more than just those who have no server to make
calls from.
Just some thoughts. I'm not fanatical about all this, and I may
well myself
be missing a point. But since this is the ACFUG "discussion" list,
that
comment seemed one worth discussing. :-)

Thanks, Charlie. Your comments were very helpful!
I have been hoping that this AJAX thing would just go away, as it
seems to
be to be a step backwards, but it looks like it will be around a
while
longer!

throw
out some clarification if it's useful, first about the JRE/CFX
issue,
then about calling the google search APIs.
