How to remove cache of a specific page

Question

when implementing authentication in laravel using sentinel and logout, then if I press the "return to one page" button of any browser, it returns to the control panel. If the page is refreshed, it goes to the login page as necessary. But I want to prevent access to the control panel without updating.

• How to remove the cache of this particular page immediately after logging out?
• How do I know any specific browser cache on a page and Laravel's approach to doing this?

NB After exiting the system and moving to the dashboard, this will prevent anything from changing as needed.

Destroy the session when you call the logout function. Just write your exit function to your controller as follows:

public function getLogout() { Sentry::logout(); Session::flush(); // Insert this line, it will remove all the session data return Redirect::to('users/login')->with('message', 'Your are now logged out!'); } 

Edit:

At first I used only Session: flush (), and somehow it worked! But when I checked again, I found that it was not working. So, we need to add another code to clear the browser cache upon logout.

Using a filter may be the solution to this problem. (I have not found another solution yet). First add this code to filters.php:

 Route::filter('no-cache',function($route, $request, $response){ $response->header("Cache-Control","no-cache,no-store, must-revalidate"); $response->header("Pragma", "no-cache"); //HTTP 1.0 $response->header("Expires"," Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past }); 

Then attach this filter to routes or controllers. I bound it to the controller build function as follows:

 public function __construct() { $this->beforeFilter('csrf',array('on' => 'post')); $this->afterFilter("no-cache", ["only"=>"getDashboard"]); }
