For IIS7

​

Merge this XML into the web.config file at the root of your application / site:

​

  <?xml version="1.0" encoding="utf-8"?>

  <configuration>

    <system.webServer>

      <httpProtocol>

        <customHeaders>

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

        </customHeaders>

      </httpProtocol>

    </system.webServer>

  </configuration>

​

If you don't have a web.config file already, or don't know what one is,

just create a new file called "web.config" containing the snippet above.
