Need quick security issue fix

I think my host changed something. I use to be able to access my AMFPHP gateway from anywhere…

Now, it’s kinda funny, I have a swf in designermichael.com/folder

It ONLY works(Can get data from amfphp) when I type in www.designermichael.com/folder, and not designermichael.com/folder.

The swf loads in both, but in only one url can it get data… lol! My gateway is accessed via a full url from the swf. Not a relative url.

The weird part is… I can access my gateway from on my PC. What gives?
