SWFs in Flex build directories aren't subject to the usual cross-domain HTTP access restrictions. the domain of the URL you're trying to access doesn't have a crossdomain.xml file that allows access from your SWF location. in order to not require a crossdomain.xml file, your SWF URL and web service URL must have the same HTTP origin (basically, the hostname part of the URL needs to be the same). if they're different, the web service HTTP server needs a crossdomain.xml file at /crossdomain.xml. a web search should turn up more information about the format and contents of this file.
Thanks, much appreciated.
I understand, I'll change it.
To have solve this more clearly, can you provide me with a link with a visual example?
i found out the answer
<!-- http://www.foo.com/crossdomain.xml -->
when i use my own website url doesn't work... i am using * right now ; so i am not sure about this?
place this xml file in your website directory - www.yourwebsite.com
place videophonelabs file in directory - www.yourwebsite.com/abc
