…without a crossdomain policy file?..

I’m having problems getting local connection to work between two SWFs on two different domains.

- BOTH files contains in frame 1 : System.security.allowDomain("\*");
- The receiving file is on a server with crosdomain policy file…wich allows all domains.

i posted same question here: [http://www.actionscript.org/forums/showthread.php3?p=618772&posted=1#post618772](http://www.actionscript.org/forums/showthread.php3?p=618772&posted=1#post618772)

but get the answer that its only possible if BOTH domains has a crossdomain policy file, but duh… i really cant beleive that macromedia guys didnt foresee that especially banners ends up on servers that you dont know/control…so therefore you cannot be sure that they have a crossdomain policy file that allows ur domain etc etc…

but if its true…then im stunned… , in my worl it made sense that you would need crossdomain policy for files other than SWF (cause SWF can contain the System.security.allowDomain("\*"), and i.e FLV cannot).
