Where can I set headers in laravel

Laravel Problem Overview

I want to set headers as array('Cache-Control'=>'no-cache, no-store, max-age=0, must-revalidate','Pragma'=>'no-cache','Expires'=>'Fri, 01 Jan 1990 00:00:00 GMT'); for all my views, currently I'm doing this in all controllers while returning views, like

$headers=array('Cache-Control'=>'no-cache, no-store, max-age=0, must-revalidate','Pragma'=>'no-cache','Expires'=>'Fri, 01 Jan 1990 00:00:00 GMT');

Redirect::to('/',301,$headers);`

So instead of writing this for each and every route can it be done in global scope, so that headers are set for every view.

I tried setting headers by creating after filter, but didn't get it to work.

Can anyone tell me where can I set the headers for all my views?

UPDATE One of my view file meta content

<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>

Now when i use Redirect::to('/',301,$headers) The header in firebug is

Cache-Control	max-age=0, must-revalidate, no-cache, no-store, private
Connection	Keep-Alive
Content-Type	text/html; charset=UTF-8
Date	Tue, 09 Jul 2013 14:52:08 GMT
Expires	Fri, 01 Jan 1990 00:00:00 GMT

And when I use Redirect::to('/');

The header in firebug is

Cache-Control	no-cache
Connection	Keep-Alive
Content-Type	text/html; charset=UTF-8
Date	Tue, 09 Jul 2013 14:52:08 GMT

Laravel Solutions

Solution 1 - Laravel

In Laravel 5, using Middleware, creating a new file, modifying an existing file:

New file: app/Http/Middleware/AddHeaders.php

<?php namespace App\Http\Middleware;

use Closure;
use Illuminate\Contracts\Routing\Middleware;

// If Laravel >= 5.2 then delete 'use' and 'implements' of deprecated Middleware interface.
class AddHeaders implements Middleware
{
    public function handle($request, Closure $next)
    {
        $response = $next($request);
        $response->header('header name', 'header value');
        $response->header('another header', 'another value');

        return $response;
    }
}

Modify existing file app/Kernel.php

protected $middleware = [
.
.
.

        'App\Http\Middleware\AddHeaders',
	];

And you're set.

There are a couple of different ways you could do this - all have advantages/disadvantages.

Option 1 (simple): Since the array is just static data - just manually put the headers in your view layouts directly - i.e. dont pass it from anywhere - code it straight in your view.

<?php
  //set headers to NOT cache a page
  header("Cache-Control: no-cache, must-revalidate"); //HTTP 1.1
  header("Pragma: no-cache"); //HTTP 1.0
  header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>

Option 2: Use view composers. You can use an App before filter to bind the header to all views in your app.

App::before(function($request)  
{
     $headers=array('Cache-Control'=>'no-cache, no-store, max-age=0, must-revalidate','Pragma'=>'no-cache','Expires'=>'Fri, 01 Jan 1990 00:00:00 GMT');

     View::share('headers', $headers);
});

Then just echo out the $headers in your view(s).

Note: you must let the view set your headers - that is why we are 'passing' the header into view for Laravel to handle. If you try and output the header itself from within a filter or something, you'll cause issues.

Edit Option 3: I just found out about this - you could try this

App::before(function($request)  
{
     Response::header('Cache-Control', 'nocache, no-store, max-age=0, must-revalidate');
     Response::header('Pragma', 'no-cache');
     Response::header('Expires', 'Fri, 01 Jan 1990 00:00:00 GMT');
});

Solution 3 - Laravel

In Laravel 4, this works for me:

In filters.php:

App::after(function($request, $response)
{
   $response->headers->set('key','value');
});

Like:

App::after(function($request, $response)
{
   $response->headers->set('P3P','CP="NOI ADM DEV PSAi COM NAV OUR OTR STP IND DEM"');
});

In Laravel 5 you can change /public/index.php line 55 and set your header for entire app:

$response->send();

with:

$response->header('Content-Type','text/html; charset=ISO-8859-1')->send();

for essample.

For future readers using Laravel 5.x, this can be handled out of the box without needing to create any custom middleware.

Laravel has the response() helper method, which you can chain headers to very easily.

use Response;
// Or possibly: use Illuminate\Http\Response; depending on your aliases used.

// Add a series of headers
return response($content)
	->header('Content-Type', 'text/xml')
	->header('X-Header-One', 'Header Value');

// Or use withHeaders to pass array of headers to be added
return response($content)
	->withHeaders([
		'Content-Type' => 'text/xml',
		'X-Header-One' => 'Header Value'
	]);

Read more about it in the documentation, because it can handle attaching a number of things; cookies, views, and more.

Solution 6 - Laravel

For Laravel >= 5.2 yet, following @Amarnasan answer , although I used mine for API calls

In Laravel 5, using Middleware, creating a new file, modifying an existing file:

New file: app/Http/Middleware/AddHeaders.php

<?php 
namespace App\Http\Middleware;
use Closure;
use Illuminate\Routing\Redirector;
use Illuminate\Http\Request;
use Illuminate\Foundation\Applicaion;


class AddHeaders 
{
    public function handle($request, Closure $next)
    {
        $response = $next($request);
        $response->header('Cache-Control', 'max-age=36000, public');
        //$response->header('another header', 'another value');

        return $response;
    }
}

Modify existing file app/Kernel.php so that you can use with each specific route

protected $routeMiddleware = [
.
.
.

        'myHeader' => \App\Http\Middleware\AddHeaders::class,
    ];

And you're set.

Then you can use it like so for individual routes or groups

$api->get('cars/all', 'MyController@index')->middleware(['myHeader']);;

Solution 7 - Laravel

Working on Laravel 4.2. I'm using filter for this, so in filters.php i have:

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

});

Than I attach this filter to routes or controllers. Controller attached looks like this for me:

public function __construct() {

        $this->beforeFilter('onestep',array('except' => 'getLogin'));
        $this->beforeFilter('csrf',array('on' => 'post'));
        $this->afterFilter("no-cache", ["only"=>"getIndex"]);
    }

This filter is attached as afterFilter.
