For ASP NET Core You can use asp-route-  attribute    lt form asp-action  Login  asp-route-previous   Model ReturnUrl  gt    Other in details example  Imagine that you have a Vehicle Controller with actions  Index  Details  Edit  and you can edit any vehicle from Index or from Details  so if you clicked edit from index you must return to index after edit and if you clicked edit from details you must return to details after edit     In your viewmodel add the ReturnUrl Property public class VehicleViewModel                                                public string ReturnUrl  get set        Details cshtml  lt a asp-action  Edit  asp-route-previous  Details  asp-route-id   Model CarId  gt Edit lt  a gt   Index cshtml  lt a asp-action  Edit  asp-route-previous  Index  asp-route-id   item CarId  gt Edit lt  a gt   Edit cshtml  lt form asp-action  Edit  asp-route-previous   Model ReturnUrl  class  form-horizontal  gt           lt div class  box-footer  gt               lt a asp-action   Model ReturnUrl  class  btn btn-default  gt Back to List lt  a gt               lt button type  submit  value  Save  class  btn btn-warning pull-right  gt Save lt  button gt           lt  div gt       lt  form gt    In your controller      GET  Vehicle Edit 5     public ActionResult Edit int id string previous                    var model   this UnitOfWork CarsRepository GetAllByCarId id  FirstOrDefault                var viewModel   this Mapper Map lt VehicleViewModel gt  model    if you using automapper       or by this code if you are not use automapper     var viewModel   new VehicleViewModel         if   string IsNullOrWhiteSpace previous                  viewModel ReturnUrl   previous              else                 viewModel ReturnUrl    Index               return View viewModel                 HttpPost      public IActionResult Edit VehicleViewModel model  string previous                    if   string IsNullOrWhiteSpace previous                   model ReturnUrl   previous              else                 model ReturnUrl    Index                                                                    return RedirectToAction model ReturnUrl

If you are not concerned with unit testing then you can simply write   return Redirect ControllerContext HttpContext Request UrlReferrer ToString

A suggestion for how to do this such that    the return url survives a form s POST request  and any failed validations  the return url is determined from the initial referral url without using TempData   or other server-side state  handles direct navigation to the action  by providing a default redirect       public ActionResult Create string returnUrl           If no return url supplied  use referrer url         Protect against endless loop by checking for empty referrer      if  String IsNullOrEmpty returnUrl           amp  amp  Request UrlReferrer    null          amp  amp  Request UrlReferrer ToString   Length  gt  0                return RedirectToAction  Create               new   returnUrl   Request UrlReferrer ToString                     Do stuff        MyEntity entity   GetNewEntity         return View entity       AcceptVerbs HttpVerbs Post   public ActionResult Create MyEntity entity  string returnUrl        try                  TODO  add create logic here             If redirect supplied  then do it  otherwise use a default         if   String IsNullOrEmpty returnUrl               return Redirect returnUrl           else             return RedirectToAction  Index              catch               return View        Reshow this view  with errors           You could use the redirect within the view like this    lt   if   String IsNullOrEmpty Request QueryString  returnUrl       gt   lt       gt       lt a href   lt    Request QueryString  returnUrl     gt   gt Return lt  a gt   lt       gt

Pass a returnUrl parameter  url encoded  to the change and login actions and inside redirect to this given returnUrl  Your login action might look something like this   public ActionResult Login string returnUrl            Do something        return Redirect returnUrl
