flex 策略文件:crossdomain.xml

总：

1、 策略文件写法：

<?xml version="1.0"?>
<!-- http://www.aeroflash.org/crossdomain.xml -->
<cross-domain-policy>
<allow-access-from domain="www.friendOfAeroflash.org" />
<allow-access-from domain="*.aeroflash.org" />
<allow-access-from domain="123.321.0.1" />
</cross-domain-policy>

2、 通配策略文件（无限制访问）：

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*"/>
<allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>

3、 Adobe 强烈不推荐的允许所有资源访问的crossdomain.xml文件：

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" secure="false"/>
<allow-http-request-headers-from domain="*" headers="*" secure="false"/>
</cross-domain-policy>
