MVC3

This is My Application default url - http://localhost:43190/.. It has some productnames displayed as Html.Routelink.. When I click that link it takes me to
http://localhost:43190/Detail/1 (or) respective Product ID..
But when I hit back the productnames are displayed as Url..

Ex:
Football
Bat

If I hit Football it will go to http://localhost:43190/Detail/1 and if I hit backspace its displayibg as url
Detail/1
Detail/2
instead of Football.. If i hit F5 its back to normal..

Here is that Routelink..

@Html.RouteLink(@Model.Name,new { controller = "Product", action = "Detail", prod = @Model.ProductID}, new { @class = "" })
