CAKEPHP Reset cookieTimeout on activity - session

I have problem to make my application is not logged out user on activity
I have code like the picture above
as we know, modify the cakephp session is able by that code
"timeout" values is used to set how long session will be expired in a minutes. and the "autoRegenerate" value is used to renew the timeout value
and the last is "cookieTimeout" is used to set how long activity allowed
the crux of my question is how to auto regenerated the cookieTimeout cakephp in core.php (like renew "timeout" value with "autoRegenerate" => true)
Thanks in advance

Understanding Laravel Session Handler

I am trying to understand Laravels session handler and can't find anything online. At the moment, in session.php I am doing
'lifetime' => 10,
I have the session driver set to file. So from what I have read, this sets the idle timeout of the session to 10 minutes.
So what does idle mean in this case? I am assuming it means if no request is sent to the server within 10 minutes it will expire. Is this correct?
Also, how can it tell if no request has been sent within 10 minutes? I have taken a look at the session file within storage, and I do not see any timestamp.
So how exactly does all of this work?
Thanks
Yes you are correct: if you don't send any request after the lifetime config value the session will be destroyed.
The Illuminate\Session\FileSessionHandler class has a gc() function, it is a garbage collector function that has a probability to be called on every request, you can control the chances with the session.lottery config value. This function destroy each session file that has a modified timestamp older than now - lifetime.
You can find the Illuminate\Session\FileSessionHandler class in the file vendor/laravel/framework/src/Illuminate/Session/FileSessionHandler.php if you want to take a look at the source code.

Redis subscriber is not notified by EXPIRE key 0

I've got a Redis client subscribed to __keyevent#0__:expired notifications. It works perfectly, either when the key expires by itself (ttl reached) or when I expire them manually with a number of seconds greater than 0, like so:
EXPIRE myKey 1
The subscriber sees the expired event and can therefore take some actions.
However, if I want to manually delete the key and have the subscriber notified, I use EXPIRE with 0 as the number of seconds:
EXPIRE myKey 0
The key gets deleted, but the subscriber doesn't receive anything.
I can't see anything related to this in the doc. Can anyone explain this behavior?
From reviewing the source code (expire.c, ~252), setting an expiry value of <=0 (or using EXPIREAT with a time in the past) results in a deletion of the key rather than an expiry (and accordingly a DEL notification rather than an EXPIRED event).
This behavior is indeed undocumented and it would be good if you could submit a PR that fixes that to the documentation repo (https://github.com/antirez/redis-doc).

Session expiring in Yii2 despite user activity

I have started using Yii2 and need to store more information about user in identity. I already know that in Yii2, this should be done using sessions like
Yii::$app->session->set('user.company_id', '121');
This works fine as I am able to get these values later in project using:
Yii::$app->session->get('user.company_id');
. However, these session values are getting wiped up despite user activity on same pages. So after 5-10 minutes, the same user sees some fields based on session value, however, after 1 minute if I refresh the session values go away which should actually happen on session close or user logout.
Any suggestions what I am doing wrong?
First check your app\config\main.php or main-local.php if it contains:
'user' => [
...
'enableAutoLogin' => true,
...
],
Second check if you have a proper assignment to the value assigned to the variable:
$authTimeout;
$absoluteAuthTimeout;

Is there a way to view the HttpRuntime.Cache?

I have a webservice that stores an authenticated users token in the HttpRuntime.Cache to be used on all subsequent requests. The cached item has a sliding expiration on it of 24 hours.
Secondly I have a vb.net app that is pinging this webservice every 15 seconds. It gets authenticated once, then uses the cached token for all subsequent requests. My problem is that the application appears to lose authentication at random intervals of time less than the 24 hr sliding expiration. However with it getting pinged every 15 sec the authentication should never expire.
I am looking for a way to view the HttpRuntime.cache to try and determine if the problem is in the webservice security methods or within the vb.net app. Can I view the HttpRuntime.cache somehow?
The webservice is part of a web forms site that was built with asp.net 2.0 on a Windows Server 2008.
The name of my key's were unknown as they were system generated guid values with a username as the value. So in order to view a cache collection that was unknown I used a simple loop as follows.
Dim CacheEnum As IDictionaryEnumerator = Cache.GetEnumerator()
While CacheEnum.MoveNext()
Dim cacheItem As String = Server.HtmlEncode(CacheEnum.Entry.Key.ToString())
Dim cacheItem2 As String = Server.HtmlEncode(CacheEnum.Entry.Value.ToString())
Response.Write(cacheItem & ":" & cacheItem2 & "<br />")
End While
Hope this helps others.
First off, HttpRuntime.Cache would not be the best place to store user authentication information. You should instead use HttpContext.Current.Session to store such data. Technically the cache is allowed to "pop" things in it at its own will (whenever it decides to).
If you actually need to use the cache, you can check if your item is in the cache by simply doing:
HttpRuntime.Cache["Key"] == null

CakePHP auth session vs. cookie not updating

I have a ACL+auth driven app. Everything works fine but I discovered that user is logged out after a random period of time. After doing some research I discovered that the cookie set once doesn't change it's expiration date on page refresh. So it goes like this:
I set up manually expiration time to 1 minute (Security.level low (with some changes in cake/libs) and timeout 60)
19:00:00 - user loads the page - cookie is set up
19:00:05 - user logs in (cookie doesn't change the expiration date)
19:00:30 - page refresh (cookie doesn't change the expiration date)
19:00:55 - page refresh (cookie doesn't change the expiration date)
19:01:05 - page refresh - user is logged out... (cookie expired after 1 minute)
So the problem is the user gets logged out after 60 seconds from setting a cookie in instead of 60 seconds of inactivity. Does CakePHP deal with cookie files automatically? Or do I have to take care about it myself?
All I did is set up a cookie name in config/core.php and setup auth. I don't have any cookie handling function, but the cookie is created itself - correctly, just isn't updated
I had the same issue and countered it with the following code which is called on every page load and ajax call.
if(isset($_COOKIE[Configure::read("Session.cookie")])){
$session_delay = Configure::read("Session.timeout") * (Configure::read("Security.level") == "low" ? 1800 : 100);
setcookie(Configure::read("Session.cookie"), $_COOKIE[Configure::read("Session.cookie")], mktime() + $session_delay, "/");
}
