Problem with Request.ApplicationPath

Hi,
I have following function

if ((userName == null) || (userName.Length <= 0))
{
   string login = Request.ApplicationPath + "/login.aspx";
   string js = string.Format ("<script langauge=\"javascript\">window.parent.location.href = '{0}';</script>",login);
   this.RegisterStartupScript("login", js);  
}

this works fine with my localhost and windows xp but on windows 2000  string login = Request.ApplicationPath + "/login.aspx"; gives only http://login.aspx instead of the whole application path/login.aspx.....does anyone know why Request.ApplicationPath  is not able to get the path on windows 2000 and how can one resolve this.
Thanks

ok..if login.aspx is in the web site root than just use the following:

if ((userName == null) || (userName.Length <= 0))
{
   string login = "http://"+Request.ServerVariables["SERVER_NAME"]+"/login.aspx";
   string js = string.Format ("<script langauge=\"javascript\">window.parent.location.href = '{0}';</script>",login);
   this.RegisterStartupScript("login", js);  
}

try replacing

Request.ApplicationPath
with

Server.MapPath(Request.ApplicationPath)

WHen you talk about the differente machines do you mean clients or have you installed your web on these servers?

If the latter have you configured the application correctly in IIS?

Forget YZlat answer. This will return the physical (folder) location of the app!

You can use something like the following:

string strURL = "http://"+Request.ServerVariables["SERVER_NAME"]+"/"+Request.ServerVariables["URL"];
string strScriptPath = Request.ServerVariables["SCRIPT_NAME"];
string[] strScriptPathArr = strScriptPath.Split('/');
string strScriptName = strScriptPathArr[strScriptPathArr.Length - 1];
strURL = strURL.Replace(strScriptName,"")+"/login.aspx";

did you try using CurrentExecutionFilePath instead?

In 2000 just put your site as a folder in c:\inetpub\wwwroot\MyApp

The in IIS click on the create application button.

Iam using this way ...and implementing it on win2k server

string userName = UtpContextManager.UserName;
 if ((userName == null) || (userName.Length <= 0))
  {
     string login;
     if(Request.ApplicationPath == null)
      {
          loginFile = "http://"+Request.ServerVariables["SERVER_NAME"]+"/login.aspx";
       }
     else
      {
         login = Request.ApplicationPath + "/login.aspx";
      }
 
  string js = string.Format ("<script langauge=\"javascript\">window.parent.location.href = '{0}';</script>",login);
   this.RegisterStartupScript("login", js);  

Let me try it ...and if this works 500 are yours :)
actually its seems that on win2k server the directory structure is different ...unlinke winxp where we get http://servername/website  in win2k its http://servername/page.aspx   the website name is not there....anyways let me implement n see..how it goes and then will get back to u
