Re: remoting object access information from local xml file frequen

Interesting. I suppose that would work but the solution I gave you will work
without IIS and the Settings object can be anything you want it to be so it
seems more flexible in this case. I have to avoid using HttpContext in our
products because the components can be deployed in a variety of physical
configurations and can't rely being in IIS.
