Just to add a little color to this about
creating a proxy in two lines J
The proxy that Flex 1.5 provides (and Flex
Enterprise Services will provide) is not a simple straightforward re-direction
to the site of your choice. We also make sure that things like cookies are
transferred correctly, protect the proxy from being used in DOS attacks,
capture header errors that the Player is unable to process and convert them for
use by the ActionScript, etc. There are a number of elements that need to be
considered when writing a true proxy for Flex apps, but with that said if you
are simply trying to access an XML file on a server or do something where no authentication
and no cookies will be needed you may be able to write a simple proxy in the
language of your choice, and that link on the labs site is a good place to get
started.

One more thing. You can write
your own proxy. Depending on which server
language you are using, and whether you need to
deal with authentication
or not, it can be as simple as two lines of code.

to implement
The model actually hasnt changed. In Flex
1.5 you could also use
the crossdomain.xml solution to allow the player
to connect to a web
service on a different host then it was downloaded
from.
Now in Flex1.5 you had the flexproxy servlet which
would act as a
proxy and redirect those calls tot he third
party. You wouldnt need
crossdomain.xml then. However, you could
bypass the proxy and then
use crossdomain.xml. All youre choice.
In Flex2 you will need the enterprise data
services to have access
to the proxy. So to do what you want, and
not rely on
crossdomain.xml in Flex2 you need the more
expensive (in line with
Flex 1.5) version.
The difference is for the much lower price you can
skip needing the
proxy *if* you own the service and can use
crossdomain.xml. If you
dont, you need the enterprise version.
Make sense?
