How to get full url of virtual root

[Thomas Jespersen]

Hi

I have a simple question:

How do I get the full url of the virtuel path of my website.

Eg. on my dev machine it is http://localhost:6786/website1 and on the
production server it will be http://www.mycompany.dk.

Request.Url.ToString

Check out a demo at : http://asp.net.do/test/requesturl.aspx

If you just want a client valid reference:
Dim root As String = Me.ResolveUrl("~")

If you actually want the whole URL to the root, you could build a function,
note it's untested but I can't think of any senarios where it wouldn't work.

Public Function AppRoot() As String
Dim appRelativeRoot As String = Me.ResolveUrl("~")
Dim originalUrl As String = Me.Request.Url.ToString
Dim pos As Integer = originalUrl.IndexOf(appRelativeRoot)
Dim path As String = appRelativeRoot
If pos > 0 Then
path = originalUrl.Substring(0, pos + appRelativeRoot.Length)
End If
Return path
End Function

Hi, Larry.

re:

Why go through those hoops, if Request.Url.ToString gets the whole URL ?

He wanted the full URL to the application root, not the page the client
requested.

OK,

even so, that's a lot easier to get with :

Dim hostname as string = Request.Url.Host
Label1.text = "http://" & hostname & Request.ApplicationPath & "/"

See it running at : http://asp.net.do/test/apppath.aspx

Why are assuming that it's http?

And then there's the port that might need to be appended.

Hi Juan

Request.ApplicationPath! Why didn't I see that. I was going nots. Thanks.

Here is the final method, which also takes the port number and protocol
(http/https) into account:

private string FullApplicationPath()
{
return Request.Url.AbsoluteUri.Replace(Request.Url.AbsolutePath,
string.Empty) + Request.ApplicationPath;
}

All the other methods simply didn't work, because they either removed the
Virtual directory or assumed that the everything else was on the same level
as the Request.

re:

Because this is an ASP.NET newsgroup ?
*All* questions here are supposed to be related to ASP.NET.

And, of course, ASP.NET works over http.

I'm glad my tip was able to get you on the right track, Thomas.

And, of course, ASP.NET also works over https. It can also include a port
number.

Hardcoding it to always be http is just a bad idea.

heh, heh...

Of course, https is just a special form of http.

Private _RootUrl As String = Nothing
Public ReadOnly Property RootUrl() As String
Get
If String.IsNullOrEmpty(_RootUrl) Then
Dim builder As New System.Text.StringBuilder
builder.Append(Request.ServerVariables("SERVER_PROTOCOL").Split("/")(0).ToLower())
builder.Append("://")
builder.Append(Request.Url.Host)
If Not String.IsNullOrEmpty(Request.ServerVariables("SERVER_PORT")) AndAlso _
Not Request.ServerVariables("SERVER_PORT") = "80" Then
builder.Append(":")
builder.Append(Request.ServerVariables("SERVER_PORT"))
End If
If Not String.IsNullOrEmpty(Request.ApplicationPath()) Then
If Not Request.ApplicationPath().StartsWith("/") Then
builder.Append("/")
End If
builder.Append(Request.ApplicationPath())
End If
If Not builder.ToString.Trim.EndsWith("/") Then
builder.Append("/")
End If
_RootUrl = builder.ToString
End If
Return _RootUrl
End Get
End Property

I'd be interested to know if this works with URL rewriting.
