I've got a bunch of url aliases can I just say *.example.com in my crossdomain.xml file and have it work?

Question

Here's my current crossdomain.xml:

<cross-domain-policy>
   <allow-access-from domain="www.example.com" />
   <allow-access-from domain="example.com" />
   <allow-access-from domain="example-alias.com.com" />
   <allow-access-from domain="www.example-alias..com" />
   <allow-access-from domain="otherexample.com" />
</cross-domain-policy>

I'm going to be adding a few other aliases and subdomians, etc. Can I simplify this to:

<cross-domain-policy>
   <allow-access-from domain="*example.com" />
   <allow-access-from domain="*example-alias.com.com" />
   <allow-access-from domain="*otherexample.com" />
</cross-domain-policy>

Answer 1

Close.

<cross-domain-policy>
    <allow-access-from domain="*.example.com" />
    <allow-access-from domain="*.mail.other-example.com" />
</cross-domain-policy>

It's slightly different (you're missing the dot). See the cross-domain policy file specification from Adobe.
