SPWeb.Url returns wrong URL

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.

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开发者_如何学Python I'm accessing the site. What am I doing wrong?

Try using:

SPContext.Current.Site.MakeFullUrl(SPContext.Current.Web.ServerRelativeUrl);

That should take into account your access mappings.

Odd...

As an alternative, have you tried using HttpContext.Current.Request.Url ?
