I have a Flex App that works locally using the flex builder
run. The Sandbox type local is localTrusted. If I put it on the
server and access it Sandbox type is remote. I ran a packet sniffer
and I see the Flash Player access my crossdomain.xml at the root of
the server I'm trying to access. I also see the crossdomain.xml
return in the packets. This means it actually got to the player and
then it still threw this security error. This is a production
problem I have not yet resolved and has been a total pain in the
*** :) It worked in system test because the two servers are on the
same physical machine in system test, but in production they are
The latest Flas Player versions have additional requirements.
You crossdomain file should look something like this below. See the
security whitepapers for more info.
