title: SPWeb.Url returns wrong URL
body: <p>I have a web application in SharePoint that has been extended to another zone (Extranet). The access URL for the default zone is http ://server1, and the URL for the extranet zone is https: //www.server1.com.</p>
  
  <p>Now, when I access the site via the extranet zone, I find that SPContext.Current.Web.Url returns http ://server1. I would have expected https ://www.server1.com, since that's how I'm accessing the site. What am I doing wrong?</p>
