I found that all the websites in one of the domains are configured with custom p3p headers. Is this done by Group Policy? If so, when item forces this configuration?
And actually we provide a p3p header in our code. Therefore there will be two p3p headers in the response and only the first is effective. Is it possible to overwrite the preconfigured p3p header in IIS6? I think IIS7 is able to so this, right?
