Set cookie max Expires to 400 days

[paulbalandan]

Description
Based on Replacement to RFC 6265, the max Expires SHOULD NOT be greater than 400 days.

Expires attributes that are greater than the limit MUST be reduced to the limit.

Thus, browsers crop the expires limit to this amount.

It is draft-ietf-httpbis-rfc6265bis-latest, not RFC 6265.

The method name withNeverExpiring() will not match the behavior.
It is better to make deprecated the method and add a new one.

[paulbalandan]

I stand corrected. The referenced internet draft is not RFC 6265, but is intended to obsolete and replace RFC 6265.

That's got some sign-off! This was just published (8/15) - anyone know the voting/implementation lifecycle of RFCs like this?

How is this a breaking change? I checked with Microsoft Edge today, and seems it is using the 400 days as expires of the request cookie. Well, aside from the tests expecting the expires of withNeverExpiring() to obviously change (but we don't have tests for that at the moment), the browser's request cookie will not have the expires at 5 years.

1. Change PHP code

diff --git a/app/Config/Routes.php b/app/Config/Routes.php
index ff2ac645c..4b1899517 100644
--- a/app/Config/Routes.php+++ b/app/Config/Routes.php@@ -36,6 +36,7 @@ $routes->set404Override();
// We get a performance increase by specifying the default
// route since we don't have to scan directories.
$routes->get('/', 'Home::index');
+$routes->get('/yard', 'Home::test');
/*

namespace App\Controllers;
+use CodeIgniter\Cookie\Cookie;+
class Home extends BaseController
{
public function index()
{
- return view('welcome_message');+ $this->response->setCookie((new Cookie('cookie', 'monsters'))->withNeverExpiring());+ return redirect()->withCookies()->to('/yard'); ++ // return view('welcome_message');+ }++ public function test()+ {+ var_dump($_COOKIE);
}
}

2. Run php spark serve
   

3. Check Developer Tools > Network. Reload page. Check for the request cookie "cookie" and look for its Expires value.
   

4. Verify date shown.

This is Firefox. At the moment, it has the expires at 5 years.

[kenjis]

Do we need the withNeverExpiring() method?
Why don't we just make it deprecated?

[MGatner]

Yes let's deprecate it. If we have a feature that inherently creates differing behavior across browsers that's a detractor. I also don't like that this is called "never expiring" but sets for five years.
