Your server side code should read the Origin request header and if it pattern matches one of your domains (http://*.mycompany.com) then you can return Access-Control-Allow-Origin: <domain> where <domain> is the actual Origin given in the request.

So if your request header is

Origin: http://foo.mycompany.com

this will match http://*.mycompany.com

so you set

Access-Control-Allow-Origin: http://foo.mycompany.com

for this response.
