How do I get the referrer URL in an ASP.NET MVC action?

Question

How do I get the referrer URL in an ASP.NET MVC action? I am trying to redirect back to the page before you called an action.

Answer 1

You can use Request.UrlReferrer to get the referring URL as well if you don't like accessing the Request.ServerVariables dictionary directly.

Answer 2

Request.ServerVariables["http_referer"]

Should do.

Answer 3

You can use this

filterContext.RequestContext.HttpContext.Request.UrlReferrer.AbsolutePath

Answer 4

To correct use reffer url you should pass it to viewModel, try so:

public interface IReferrer
{
    String Referrer { get; set; }
}

...

public static MvcHtmlString HiddenForReferrer<TModel>(this HtmlHelper<TModel> htmlHelper) where TModel : IReferrer
{
    var str = htmlHelper.HiddenFor(_ => _.Referrer);
    var referrer = HttpContext.Current.Request.UrlReferrer.AbsoluteUri;
    return new MvcHtmlString(str.ToHtmlString().Replace("value=\"\"", String.Format("value=\"{0}\"", referrer)));
}

...

@Html.HiddenForReferrer()
