Checking External Server Connection

Hi guys and gals,

I’ve got a swf called checkconnection.swf and basically this runs off and checks to see if it can get info from our online catalogue servers, however this swf is hosted at our IPS and our servers are here at our building on a different network with a different net address.

When I run the program from the flash program it works fantastic. When I transfer my swf over to our ISP it fails. Can flash check an external source?

So lets say, for example my flash file is hosted at and my server is at can flash view, post and get things over a different domain? Is there a way to force flash to do this?

Thanks to anyone that can help.
