Hi,

I have an swf hosted on let’s say [http://www.domain.com](http://www.domain.com). I want to allow it to access my localhost. So in the root of my localhost, I’ve placed the crossdomain.xml file:

\<?xml version=“1.0”?\>  
\<!DOCTYPE cross-domain-policy SYSTEM “[http://www.adobe.com/xml/dtds/cross-domain-policy.dtd](http://www.adobe.com/xml/dtds/cross-domain-policy.dtd)”\>  
\<cross-domain-policy\>  
\<allow-access-from domain="\*" /\>  
\</cross-domain-policy\>

I can access it through [http://127.0.0.1/crossdomain.xml](http://127.0.0.1/crossdomain.xml). In firebug I see that the swf is making the request for it and the status is 200 OK. Still the flash player throws the "Error #2048: Security sandbox violation: [http://www.domain.com/theflash.swf](http://www.domain.com/theflash.swf) cannot load data from [http://127.0.0.1/somescript."](http://127.0.0.1/somescript.%22) What can be wrong? I don’t know what else to try. I did a lot of searching about this issue, all the relevant information i found was about the crossdomain.xml file, and I think I got that one right.

Thank you and have a nice day!
