CORS on IIS7 Adding required headers for underlying CORS handling

For Microsoft IIS7, merge this into the web.config file at the root of your application or 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.
