First off, I'm new to the forum, however I have been using DNN for a while now and I am an ASP.NET developer. I have not gotten too deep into the coding behind DNN, but I have a fair understanding.

I have installed DNN into a virtual directory: http://www.mydomain.com/myvirtual 

I have configured the following entry in my web.config: <add key="HostHeader" value="/myvirtual" /> in order to have DNN filter out the /myvirtual application and make the site function as if it were hosted at the root level.

Now for my issues:

First - The install configured my default alias as: www.mydomain.com/install. I manually changed this in the SQL table and the site started and works fine. The issue I'm reporting here is the default install does not account for the "HostHeader" configuration properly.

Second - The default subhost.aspx does not account for the "HostHeader" configuration either. I have updated as follows:

<%@ Page Language="VB" %>
<%@ Import Namespace="DotNetNuke" %>
<script runat="server">
  Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    Dim DomainName As String
    Dim ServerPath As String
    Dim ServerPathURL() As String
    Dim URL() As String
    Dim intURL As Integer
    Dim HostHeader As String
    ' parse the Request URL into a Domain Name token 
    URL = Split(Request.Url.ToString(), "/")
    ' get the host header setting from web.config
    HostHeader = Right(Config.GetSetting("HostHeader").ToLower, Len(Config.GetSetting("HostHeader")) - 1)
    For intURL = 2 To URL.GetUpperBound(0)
      Select Case URL(intURL).ToLower
        Case "admin", "desktopmodules", "mobilemodules", "premiummodules"
          Exit For
        Case HostHeader
          ' filter the host header by skipping to the next
        Case Else
          ' check if filename
          If InStr(1, URL(intURL), ".aspx") = 0 Then
            DomainName = DomainName & IIf(DomainName <> "", "/", "") & URL(intURL)
          Else
            Exit For
          End If
      End Select
    Next intURL
    ' format the Request.ApplicationPath
    ServerPathURL = Split(Request.ApplicationPath, "/")
    For intURL = 0 To ServerPathURL.GetUpperBound(0)
      Select Case ServerPathURL(intURL).ToLower
        Case HostHeader
          ' filter the host header by skipping to the next
        Case Else
          ServerPath = ServerPath & IIf(ServerPath <> "", "/", "") & ServerPathURL(intURL)
      End Select
    Next intURL
    
    If Len(ServerPath) > 0 Then
      If Mid(ServerPath, Len(ServerPath), 1) <> "/" Then
        ServerPath = ServerPath & "/"
      End If
    Else
      ServerPath = "/"
    End If
    DomainName = ServerPath & "Default.aspx?alias=" & DomainName
    Response.Redirect(DomainName, True)
  End Sub
</script>

Now the child portal redirection functions properly. However, I am experiencing some anomalies and would like to know if this is to be expected or if there are plans to change the functionality.

Lets say I have a child portal with the alias of: www.mydomain.com/childportal, when the redirect occurs, the new URL is: http://www.mydomain.com/default.aspx?alias=www.mydomain.com/childportal and the portal site comes up. Now if you click on the "Home" breadcrumb you are then redirected to the following URL: http://www.mydomain.com/childportal/Home/tabid/<portalhometabid>/Default.aspx, which is actually what I would like to happen directly from the subhost.aspx, but I am not sure if that is possible or not. Now, if you click on the "Home" breadcrumb again you are redirected to yet another URL: http://www.mydomain.com/myvirtual/Home/tabid/<portalhometabid>/Default.aspx. And from now on you stay on the /myvirtual/ directory structure. Why does this happen? And how can I keep everything under the /childportal/ directory structure?

My apologies for posting such a long and complicated first post, but the anomalies are very much dependent on the steps as I have indicated.

Just curiosity, how is your HTTPAlias defined in the PortalAlias table???
