Tomcat的跨区域访问

Tomcat的跨区域访问

如果在Unity3D中或者Flex中访问tomcat会出现访问协议异常 做下面的配置即可解决



crossdomain.xml 位置 将这两个文件放在tomcat主目录下即 %TOMCAT_HOME%\webapps\ROOT 下可以避免不同项目相互访问资源导致的权限问题。

web访问位置http://your_host:port/crossdomain.xml，成功访问该文件即可。

1.crossdomain.xml

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