When calling a cross-domain service, Silverlight will check for the existence of clientaccesspolicy.xml first. This is the format defined by Silverlight and provides a pretty flexible way to define who can access what services. If not found, it will then default to look for crossdomain.xml, which is the file format implemented for Adobe Flash. It is important to note that this file will also still work for most public web services.
