Question

I was wondering if anyone can shed some light on cookie management. More precisely I would like to know how I could set up an initial cookie/s when a user start a session in a website.

Currently the ASP.NET_SessionId cookie is located on user computers when they navigate to the domain. I would like to set up an additional cookie with details of languageid and countryid with default parameters the first time the user navigate to the site.

Do anyone knows if there is any technique to do this, such as through web.config set up or placing cookie details using layout.cshtml like

Response.Cookies["language"].Value = "1";

Response.Cookies["country"].Value= "7";

or similar?, any option will be appreciated.

You could do this in an action filter:

public class LocalizationAwareAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var httpContext = filterContext.HttpContext.Current;

        if (!httpContext.Cookies.Keys.Contains("language"))
        {
            httpContext.Response.AppendCookie(new HttpCookie("language", 1));
        }
        if (!httpContext.Cookies.Keys.Contains("country"))
        {
            httpContext.Response.AppendCookie(new HttpCookie("country", 7));
        }
    }
}

The filter can be applied globally, so you don’t have to worry about remembering it on each action method or controller.
