Cross Domain XML
Thursday, February 14th, 2008Adobe Flash Player can be used to create applications that load data from public services and APIs. Flash can load data across domains on a permission basis (permission from the server). This is done by the server having a small crossdomain.xml file that specifies whether Flash can connect to services on that server.
Apparently I need to pay attention to this file if I want to be able to serve up a resource using the http:// scheme on localhost, and access it using a SWF file that was loaded using the file:// scheme.
Nothing's infallible of course, but I suppose this crossdomain.xml file is a reasonable way to allow opt-in usage of resources from Flash.
