I have a working website with DNN 4.1.1 .. currently it is working on a .com domain . Now I've registered another domain name with .net for the same site. what I want is when somebody access the site with .net domain it should redirect to the .com domain and rest of the site should work from there.

what shall I do for that.. do I have to do something in SiteUrls.config ???

I have no idea.. please help me in this regard

Thanks in advance

Using the wildcard feature of the Portal Alias is probably not the way you want to go.
It causes a 302 "temporarily moved" redirect which is not good for SEO.

Here is another way:

301 Redirects in DotNetNuke

< s cript runat="server">
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
      If Request.Url.Host.ToLower().EndsWith(".net") Then
        Response.Status = "301 Moved Permanently"
        Response.AddHeader("Location", Request.Url.Scheme & "://" & Request.Url.Host.Replace(".net",".com") & Request.Url.PathAndQuery)
        Response.End
     End If
End Sub

< /s cript>
