It's not controlled in the .map file, it's in the HTML request. If you're making WMS requests make sure your url contains: ?REQUEST=GetMap&SERVICE=WMS&VERSION=1.3.0 or if you're using the legacy mapserv requests: ?mode=map Either of those will prevent mapserv from writing the image file to your server and pass the image directly back to your app.
