asp实现跨域名

[xtxc]

Response.AddHeader "Access-Control-Allow-Origin", "*"
加了这个无效
又在网上找了这些
Response.AddHeader "Access-Control-Allow-Methods", "POST, GET, OPTIONS"
Response.AddHeader "Access-Control-Allow-Headers", "Content-Type, Authorization, Accept,X-Requested-With"
仍然无效，请问asp要添加什么内容，才能实现跨域访问呢？

[xtxc]

在本地hondy访问本地跨域localhost
出错提示：Failed to load http://localhost/html?mid=15: Redirect from 'http://localhost/html?mid=15' to 'http://localhost/html/?mid=15' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://hondy' is therefore not allowed access.

你是想给第三方网站提供接口访问
还是asp自己访问第三方的网站？
