About the crossdomain.xml file

Hello,

I would like to know what this files (crossdomain.xml, /flash/crossdomain.xml and /modules/boonex/open_social/crossdomain.xml)

Should I edit it?

By default it is like this

"<?xml version="1.0"?><cross-domain-policy><allow-access-from domain="*" /></cross-domain-policy>"

but I noticed that in www.boonex.us it is like this

"<?xml version="1.0"?>

<cross-domain-policy>

<allow-access-from domain="boonex.us" />

<allow-access-from domain="www.boonex.us" />

</cross-domain-policy> "

Should I put something, domain name ... ?
