There are two types how to enable CORS (Cross Origin Resource Sharing), one simply add Access-Control-Allow-Origin header value for each request that requires CORS support. Five the value of this header is “*” to grant access from any domain.

HttpContext.Response.AppendHeader("Access-Control-Allow-Origin", "*");

Or you simply add in web.config to access in full application like this.

<system.webServer>

<httpProtocol>

<customHeaders>

<clear />

<add name="Access-Control-Allow-Origin" value="*" />

</customHeaders>

</httpProtocol>
