Chamara,

Form adobe: Cross-domain policy file specification

A cross-domain policy file is an XML document that grants a web client�??such as Adobe Flash Player, Adobe Reader, etc.�??permission to handle data across multiple domains.

From ArcGIS API for FLEX help: About using crossdomain.xml

To access data from a different server other than the one hosting your Flex application, the remote server needs to have a cross-domain file in the root directory.

From ArcGIS FLEX Viewer help: Getting Started

If this service is not running in the same web server, your ArcGIS Server will need a crossdomain.xml file.
...

Your ArcGIS server (or any other used server) must return http://server.arcgisonline.com/crossdomain.xml

or

use proxy.
