In my sample I have two controllers for a bus service the bus routes and bus route stops. if a route hasn't been selected I need to redirect back to the bus route index. I
When I go directly to the bus route stop controller it should throw me back to the bus route list but it doesn't.
public ActionResult Index()
{
string busRouteCode = "";
//checks query string to see if empty
if (Request.QueryString == null)
{
//checks the cookies to see if empty
if (Request.Cookies["busRouteCode"] == null)
{
//if empty returns to bus route controller.
return View("index", "snBusRoutes");
}
else
{
busRouteCode = Response.Cookies["busRouteCode"].Value;
}
}
else
{
busRouteCode = Request.QueryString["busRouteCode"];
}
var routeStops = db.routeStops.Include(r => r.busRoute).Include(r => r.busStop);
return View(routeStops.ToList());
}
