I'm new to Umbraco. I wasn't sure if I should use a surface controller or a custom controller for this scenario. I decided on custom controller mainly because I need the action to get called even if someone copies the action link to the browser.

I want to change the language in a cookie:

public class HeaderController : RenderMvcController
{
    const string cookieName = "langCookie";

    public override ActionResult Index(RenderModel model)
    {
        //Do some stuff here, then return the base method
        return base.Index(model);
    }


    [HttpPost]
    public ActionResult LanguageCookieSet(RenderModel pModel, string pLang)
    {
        var langCookie = new HttpCookie(cookieName);
        var now = DateTime.Now;

        if (!string.IsNullOrWhiteSpace(pLang))
        {
            langCookie.Value = pLang;
            langCookie.Expires = now.AddDays(60);

            // Add the cookie.
            Response.Cookies.Add(langCookie);
        }

        return base.Index(pModel);
    }

    [HttpGet]
    public string LanguageCookieGet()
    {
        var langCookie = new HttpCookie(cookieName);
        langCookie = Request.Cookies[cookieName];

        return langCookie.ToString() ?? string.Empty; 
    }
}

On the view I tried calling it using: Url.Action like so: (didn't work) @Html.Action("LanguageCookieSet", "Header", new { pModel = this, pLanguage = "en" })"

Then I tried: (also doesn't work)

Error: No route in the route table matches the supplied values.

Any suggestions will be very much appreciated.
