Hello there,

I have a Flash form which gets submitted to a ASP page which sends the form data to a pre-defined email address. Everything seems to work fine when I compile it on my local Windows box. The issue arises when I upload these files onto the web server.

Thing is, the SWF resides on a Linux server and the ASP script resides on a Windows server. For this I have used the “System.Security.allowDomain” method in the SWF to validate the domain address of the Windows server. And it isn’t working!

Could someone tell me where am I going wrong? Is it even possible to get it working in this manner?

Regards,

---

The sandbox security in Flash dictates that it is the _remote_ source that must allow access. So “System.Security.allowDomain” is to let movies from the named domain access it.

You need to put a crossdomain.xml file in the root folder of the domain associated with the ASP-server.
