How do I get the referrer URL in an ASP.NET MVC action?
You can pass referrer url to viewModel, in my opinion it's better approach than sharing via the state, 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(hh => hh.Referrer);
var referrer = HttpContext.Current.Request.UrlReferrer.AbsoluteUri;
return new MvcHtmlString(str.ToHtmlString().Replace("value=\"\"", String.Format("value=\"{0}\"", referrer)));
}
...
@Html.HiddenForReferrer()
You can use this
filterContext.RequestContext.HttpContext.Request.UrlReferrer.AbsolutePath
Request.ServerVariables["http_referer"]
Should do.
You can use Request.UrlReferrer
to get the referring URL as well if you don't like accessing the Request.ServerVariables
dictionary directly.
