How to set Response Headers in sap web dispatcher

Hi all,

We are facing cross origin issues, while calling sap net weaver gateway server from internet(outside)

Our architecture is as below

internet-->DMS server(sap web dispatcher and reverse prosy)--> sap net weaver gate way

in sap web dispatcher we are terminating SSL.

I googled it. to solve cross domain error we need to set the response headers access-control-origin = *

But in sap web dispatcher how to set?

thanks
