Angular 5: remove route history : <p>In my app I have a category page that has links to a various product list pages.  If it turns out that when you get to a product list page there is only one product then it automatically navigates to that product detail page.  What I want is to remove the product list page route in the history so that when the user is on the product detail page and hits the back button they will go to the category page and not the product list page because that will just redirect them back to the detail page.</p>
