System.Web.HttpRequest.ServerVariables' denotes a 'property' where a 'method' was expected
Mu code is as follows :

string strVariable;
strVariable = HttpContext.Current.Request.ServerVariables("HTTP_REFERER");

if (Page.IsPostBack ==false)
{
Session["LastPage"] = Request.ServerVariables("HTTP_REFERER");
}
