I think you will. Flash Player is very strict about what it considers the same domain.

I am hosting a Flex based application on Amazon Cloud. The swf file for this app would be served from a url which looks something like https://ec-sfdkmds- <https://ec-sfdkmds-sifdhsu.pilot-1.amazonaws.com.> sifdhsu.pilot-1.amazonaws.com. This swf would be needed to make http calls to url https://ec2. <https://ec2.amazonaws.com...which> amazonaws.com...which is essentially the same domain, but a different host. Would I need a croosdomain policy file on https://ec2. <https://ec2.amazonaws.com> amazonaws.com ? ..and are there any Flash Player/Browser version related dependencies here ? Thanks DD
