I've seen several solutions to doing this but I have yet to get one to work...

I have a website that I'm trying to get (from login) to open a web application in a new window. Once the user logs in and gets validated I set some session variables and then choose the page the user goes to based on their security level. If I use the response.redirect() then it works fine... just doesn't open in a new window but my point is that I know the user is being validated. But if I try to call the javascript (or build the javascript) from codebehind it immediately takes the app to the logout screen.

Here is the last piece of code I tried
        Dim sb As System.Text.StringBuilder = New System.Text.StringBuilder()
        sb.Append("<script language='javascript'>")
        sb.Append("'webapp.aspx', '', 'resizable=yes, menubar=no, toolbar=no,   status=no, location=no, channelmode=yes')<")

        If Not ClientScript.IsClientScriptBlockRegistered(Me.GetType(), "PopupScript") Then
            ClientScript.RegisterClientScriptBlock(Me.GetType(), "openPopUp", sb.ToString())
            'ClientScript.RegisterStartupScript(Me.GetType(), "openPopUp", sb.ToString())
        End If

Open in new window

you can see I have tried a couple different methods... I've tried several others also including this one.
Dim url As String = "~/webapp.aspx"
        ClientScript.RegisterStartupScript(Me.GetType(), "openwin", "<script>openPopUp2('" & url & "')</script>")

function openPopUp2(url) {
  , "", " resizable=yes, menubar=no, toolbar=no, status=no, location=no, channelmode=yes");

Open in new window

I put the alert in there just to see if it was even hitting the javascript code and it is not... not sure what to try next.
