What is Crossdomain.xml

[kiran1989]

Can some one tell me what is the use of crossdomain.xml? And how it works? Where it should be the crossdomain.xml file is placed in client side or on remoting server?

Have you looked at these Adobe documents?

I have seen that documentation. Can any one elaborate this?

If you have a Flash movie in a given domain on one server, you cannot access data on another domain. This is a security precaution. In order to use data from another domain, you have to allow that other data to be shared by including a crossdomain.xml file in the second domain. This crossdomain.xml file tells the flash player that data coming from this second domain is OK to use.

There are a number of scenarios explained in the first document that I listed above. Do you have a situation that is different from all of those examples?
