get the path info when it's without default.aspx

[vbbit]

I need the if statement to do something. This would not work because anything after that schema "/" will always be there. I put the below code in the BeingRequestion method in global and it executes every time. I only one to rewrite the url when the "test" user is provided.

Uri uri = new Uri(Request.Url.ToString());
            Response.Write(uri.AbsoluteUri.ToString());
            Response.Write(uri.PathAndQuery.ToString());
            if (uri.PathAndQuery.Length  > 0) //this is what I need
            {
                string sUser = System.IO.Path.GetFileNameWithoutExtension(Request.PhysicalPath);
                app.Context.RewritePath("~/default.aspx?user=" + sUser);
                
            }
