Security sandbox question: how to test locally with remote files?

Question

If I have a flash file that I'd like to test locally (on my computer) but I have video files on a flash video server and photos on another server, is there an easy way to set up my flash file so I can do this?

If you have access to the remote servers, you need to upload a CrossDomain.xml file to the root of their webserver, allowing access to your machine:

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM
"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd"&gt;
<cross-domain-policy>
    <!-- Use one of the following:  -->
    <allow-access-from domain="*.example.com"/>  <!-- Your domain -->
    <allow-access-from domain="192.168.0.0"/> <!-- Your IP address -->
</cross-domain-policy>

If you don't have access, you need to set up a proxy - ie., a local server which will forward your requests through to the destination server. A little more complex, but tools such as LCDS or BlazeDS will do this for you.
