headers

I read somewhere the you can't remove response headers once they've been added. Given that, I'm wondering where in a standard ASP.NET web forms application do response headers get added initially. For example, these:

Date Fri, 23 Apr 2010 16:25:56 GMT
Server Microsoft-IIS/6.0
X-Powered-By ASP.NET
Cache-Control private

And can I stop it from happening? Do subsequent headers override old headers? Does my question even make sense?

Thanks.
