Laravel Not Adding Custom Headers

Question

Using laravel, I am attempting to add my own headers to all responses from the server.

I have the following in filters.php:

App::after(function($request, $response)
{
    // security related 
    $response->headers->set('X-Frame-Options','deny'); // Anti clickjacking
    $response->headers->set('X-XSS-Protection', '1; mode=block'); // Anti cross site scripting (XSS)
    $response->headers->set('X-Content-Type-Options', 'nosniff'); // Reduce exposure to drive-by dl attacks
    $response->headers->set('Content-Security-Policy', 'default-src \'self\''); // Reduce risk of XSS, clickjacking, and other stuff
    // Don't cache stuff (we'll be updating the page frequently)
    $response->headers->set('Cache-Control', 'nocache, no-store, max-age=0, must-revalidate');
    $response->headers->set('Pragma', 'no-cache');
    $response->headers->set('Expires', 'Fri, 01 Jan 1990 00:00:00 GMT');
    // CRITICAL: do NOT delete
    $response->headers->set('X-Archer', 'DANGER ZONE');
});

Yet no new headers show up when I test it:

[tesla | ~] => curl -o/dev/null -s -D - localhost
HTTP/1.1 200 OK
Date: Wed, 10 Dec 2014 23:13:30 GMT
Server: Apache
X-Powered-By: PHP/5.6.2
Content-Length: 974
Content-Type: text/html; charset=UTF-8

[tesla | ~] =>

I have no error or warnings in my log files. How could this be?

Answer 1

Try this out: In the controller function that calls the view, follow with a call to the 'Response' class:

$contents = View::make('your_view')->with('data', $data);
$response = Response::make($contents, 200);
$response->header('X-Frame-Options','deny'); // Anti clickjacking
$response->header('X-XSS-Protection', '1; mode=block'); // Anti cross site scripting (XSS)
$response->header('X-Content-Type-Options', 'nosniff'); // Reduce exposure to drive-by dl attacks
$response->header('Content-Security-Policy', 'default-src \'self\''); // Reduce risk of XSS, clickjacking, and other stuff
    // Don't cache stuff (we'll be updating the page frequently)
$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');
return $response;

Of course you could refactor the above and include it in a helper function.
