In FB 3 have an HttpService request that works fine running
from within Flex Builder environment.
When I deploy the application to the same server to which I
do the http request it also works on the client.
When I deploy to a tomcat localhost and retrieve the app from
localhost, I run the client on my localmachine that does a
httpRequest to another server I get a sandbox violation,
nothwithstanding that I have the crossdomain file on the server.
