We have an HTTP server (redwood) that sits in front of our
application server (sycamore). We use a virtual host-name (sspasd),
which binds to redwood on the DNS server to access the applications
through redwood forwarded to sycamore. The URL for our application
(where the Flex application resides) is
and the URL for the WebService is
If we use the virtual host name (sspasd) to load the
application and use any of redwood, sycamore, or sspasd to load the
WSDL in Flex, the WSDL loads without error, but when we attempt to
call a method in the WebService, we get a "Security error accessing
We've added crossdomain.xml files everywhere except the DNS
server that sits above the HTTP server because we don't have
control over that server.
Is there any way to use Flex WebServices with virtual host
names? If so, how?
