Alternative Hostname for an IIS web site for internal access only | I'm using IIS in Windows 2003 Server for a SharePoint intranet.   
External incoming requests will be using the host header `portal.mycompany.com` and be forced to use SSL.


I was wondering if there's a way to set up an alternate host header such as   
`http://internalportal/`   
which only accepts requests from the internal network, but doesn't force the users to use SSL.


Any recommendations for how to set this up?
