You can use Request.UrlReferrerto get the referring URL as well if you don't like accessing the Request.ServerVariablesdictionary directly.
Request.UrlReferrer如果您不喜欢Request.ServerVariables直接访问字典，也可以使用获取引用 URL 。

You can pass referrer url to viewModel, in my opinion it's better approach then sharing via the state, try so:
您可以将引用网址传递给 viewModel，在我看来，这是通过状态共享更好的方法，请尝试：
public interface IReferrer
{
String Referrer { get; set; }
}
...
...
public static MvcHtmlString HiddenForReferrer<TModel>(this HtmlHelper<TModel> htmlHelper) where TModel : IReferrer
{
var str = htmlHelper.HiddenFor(hh => hh.Referrer);
var referrer = HttpContext.Current.Request.UrlReferrer.AbsoluteUri;
return new MvcHtmlString(str.ToHtmlString().Replace("value=\"\"", String.Format("value=\"{0}\"", referrer)));
}
...
...
@Html.HiddenForReferrer()
