codeigniter session data gets lost - codeigniter

i already posted this question but still wasnt able to resolve this issue.
seems that everyone has this problem with codeigniter .
When i set my session in a controller it works perfectly and i can display it.
WHen i move to another controller, the (CUSTOM) session data is completely lost.
i tried changing my cookie_domain in config.php. Since i am on localhost i tried localhost with without / and localhost/codeigniter and sodeigniter all did not work. i am lost
btw, i read somewhere that this happens when 2 ajax requests happen at the same time. could that be the problem?
Or maybe tell me how you resolved the problem if you had same issues
screw this, i am swithing to php native sessions. if anyone wants to do that,
http://codeigniter.com/wiki/PHPSession

Check and double-check your code or any external libraries you are using for a stray sess_destroy(). I ran into a similar problem where I was storing an id in the session for reference but if the user then logs in the SimpleLogin library I was using for logins just destroys the entire session including data I did not want to lose.
This is what I get for not writing my own code.

Laravel 5.1 randomly dropping session data

I have a strange issue with a Laravel 5.1 application.
Intermittently, it’s dropping session data. I’m detected this by writing some middleware that writes the contents of the session for that request to the log file. Although the session ID (Session::getId()) doesn’t change, the value of _token in the session data retrieved with Session::all() does.
As I say, this happens intermittently. I can refresh the same URL multiple times, and then randomly on one refresh the session data’s gone, and the _token value’s different from the previous requests.
What would cause this? I’ve also noticed the flash object isn’t in the “dropped” session data.
Below is a snippet of the log. You can see the content of the session_data key randomly changes “shape” in the last two lines, but the session ID remains constant.
Also, not sure if it’s pertinent, but I have DebugBar enabled.
UPDATE: Through debugging, I’ve found that on some page loads the session is completely empty, as in, no _token (hence a new one getting generated). Nothing.
If you're using the file driver, you could run into race conditions on concurrent requests. The file then gets truncated, Laravel can't read it, so it refreshes the session. Race conditions can also lead to a symptom where something you're putting to the session just doesn't get put. This tends to be random, so it's very hard to debug. According to the Laravel team, this is a known limitation of the file driver and it does not appear to be getting fixed, so I would suggest using a different driver. This would fix your issue of random session refreshes, but it still introduces a possibility of making a change to the session that doesn't get added. As far as I know, at this point with Laravel 5.1, you'll have to manage that yourself.
Somehow your session data is too long and being truncated. If you're using the database driver (haven't tested other drivers), and you try to save session data that's longer than the field length, then subsequent requests won't be able to pull from this session, and you'll wind up with a new session. If this issue is happening randomly with very short session data, then it's probably the cause listed above.
If you use Linux, Try using Redis (http://redis.io) as session / cache manager in laravel. I had some issues in the past with text / cookies and laravel in some servers. When I instaled Redis I had no problems anymore.
More info: https://laravel.com/docs/5.1/redis
Using a different driver like memcached did not solve the problem for me.
Here is a package that implements session locking which works and very simple to incorporate in your projects.

Sporadic redirects on secondary magento store page

Recently transferred my Magento 1.7 store to a new host, and started having a frustrating problem.
We've got the store sitting behind a login shell - you can see it at http://www.seacadetshipsstore.com. Base exchange takes you to the root store (/magento/), and the gearlocker login takes you to a secure sub-store (/magento/gearlocker/).
The problem is, ever since transferring to the new host, /magento/gearlocker/ is sporadically redirecting to /magento/. I can only reproduce it 1 in every 10 times, but customers are constantly complaining that they can't access the secure store for this reason.
I've also noticed that if I turn off the security and have clients navigate to /magento/gearlocker/ directly, it seems to fix the problem for most - they no longer get the redirect after logging in. Only a few of them still have the error, and they're all PC users on various browsers.
I've set up a demo login for stack:
https://www.seacadetshipsstore.com/login.php
U: stack_login
P: thanks
I doubt it's an issue with the base url or base link url, otherwise the error would be much more consistent. I've gone through magento's official tutorials and made sure the secondary store was set up properly (remember, it was working fine on the old host). I also know it's not anything to do with the login shell - all it does is validate the user's login and redirect to /magento/gearlocker/.
Can anyone reproduce this error? Can anyone tell me what's going on, or how I might fix it? Thanks in advance!

Login & Session not working on localhost using codeigniter & Ion_Auth

I have a live site which works fine and can be logged into no problems. I have a local copy of that site but for some reason the session isn't working. If i login, i can tell that the login has worked as it tries to redirect to the success page and i can see that a new session gets started.
But, the system doesn't recognise me as being logged in.
I've changed the cookie_domain config variable, changed session_ip and session_user_agent matching variables but nothing seems to work.
Also, i increased the size of the fields that hold session/userdata data in the db to longtext to make sure nothing was being chopped off.
Is there anything i've missed, anything that i've forgotten?
Ahhh, my bad. I didn't realise i had a dev only config in there that needed to have it's cookie domain changed. Whoops!!

Zend_Session and Zend_Log _Db are both writing to the database twice for every page load

There are plenty of examples of similar problems littered around the web but none of their solutions seem to fix this particular variation. Any suggestions would be appreciated.
Usually this problem occurs because a rogue link is causing a request for a resources like a favicon or css file to hit the dispatcher more than once, thus causing multiple dispatch processes and therefore multiple rows in your database.
I have checked that all the links on this very simple example page do actually resolve to the resource to which they point.
The session handler is setup as follows:
Zend_Db_Table_Abstract::setDefaultAdapter($db);
Zend_Session::setSaveHandler(new
Zend_Session_SaveHandler_DbTable($config->session->toArray()));
The db logging is setup as follows:
$writer = new Zend_Log_Writer_Db($db, $config->log->tableName,
$config->log->columnMap->toArray());
$logger = new Zend_Log($writer);
Both objects are correctly setup and can read and write to and from the database. Only everything happens twice. If I put a test log message anywhere in the application it is written into the database twice. If I increment three variables with every call to the index action - one stored in the session, one passed around via a Zend_Registry object and another local to the indexAction - only the session variable is incremented by 2. The Apache access log shows the correct amount of requests being fired from the page load and all have good response codes of either 200 or 304 (unchanged).
I have tried disabling all head links.
I have tried disabling the layout entirely.
I have localised everything to the dispatcher and exited before dispatch is run.
In all cases the extra write/increment takes place.
Any thoughts?
Thanks in advance for any help.
I seem to have found and fixed the issue. Chrome (and possibly all Webkit browsers) issues an additional HEAD request on top of the GET which means the application is hit twice and anything session based will be triggered as a result of both requests. My temporary solution is to put the following code near the start of my index.php file.
if ("HEAD" == $_SERVER['REQUEST_METHOD']) {
exit;
}
I hope that helps anyone with the same issue.
Google Chrome always asks for the favicon.ico by making annoying requests to the server. Take care about this in Chrome.

Zend framework session expires prematurely

I'm using Zend Framework for PHP and handling sessions with the Zend_Session module. This is what I have in my Initializer (or bootstrap):
Zend_Session::start();
Zend_Session::rememberMe(864000);
864000 seconds should be good for 10 days, but I'm still being kicked out at about an hour (or maybe a little less). I've tested to see if this statement works at all by setting it to 10 seconds, and indeed I am kicked out at the appropriate time, but when I set it to a very high value, it doesn't work! I went through some of the documentation here:
http://framework.zend.com/manual/en/zend.session.html
Another method I saw was to use the following:
$authSession = new Zend_Session_Namespace('Zend_Auth');
$authSession->setExpirationSeconds(3600);
Now, I have different namespaces. Does this mean I have to set this for all of them if I want to keep them from expiring? I haven't tested this method of setting the expiration, but I really wanted to see what the gurus on here had to say about what the correct way of approaching this problem is. Thanks a lot guys...
Also, does anyone know how I can make it so that the session never expires? I've tried setting the second to 0 and -1, but that throws an error.
I had the same problem and solved it by putting:
resources.session.save_path = APPLICATION_PATH "/../data/session/"
resources.session.gc_maxlifetime = 864000
resources.session.remember_me_seconds = 864000
in the application.ini (as suggested by tawfekov) and
protected function _initSessions() {
$this->bootstrap('session');
}
in the Bootstrap.php (this I typically forgot at first). You have to give the session directory the correct access rights (chmod 777). I described the issue here. Hopefully this will help the next person with the same issue.
Your client's computer clock, date, AND time zone need to be set correctly for session expirations to work. Otherwise the time conversions are off, and likely causing your cookie to expire the minute it hits the their browser.
Try calling remember me before starting the session:
Zend_Session::rememberMe(864000);
Zend_Session::start();
Otherwise I believe it will use the default of remember_me_seconds. See 49.4.4. rememberMe(integer $seconds)
Also, does anyone know how I can make
it so that the session never expires?
I've tried setting the second to 0 and
-1, but that throws an error.
I don't think that is possible. The session is controlled by whether the cookie exists on the users computer. Those cookies can be deleted, even by the users if they clear their cache. I think the best you can do is set it to a very large number. Say 12 months.
I guess you are using ZF 1.8 or above ,
so you can put in the config.ini file
resources.session.save_path = APPLICATION_PATH "/../data/session"
resources.session.remember_me_seconds = 864000
and these setting will automatically loaded
again only in ZF 1.8 or above if not you had to load these config manually
i hope it helps you :)
Are there other PHP applications running on the server?
Assuming you're using the standard, file-based, session handler, PHP will store all sessions in the same place (typically /tmp).
If you have some other script on the server using the default session_gc_maxlifetime settings, it may be eating your session files.
The easiest fix to try is to configure PHP to store session files for this application someplace special -- that way other apps running on the server will never accidently "clean up" session data from this app.
Try creating a directory like /tmp/myAppPhpSessions (or whatever), and adding:
ini_set('session.save_path','/tmp/myAppPhpSessions');
ini_set('session.gc_maxlifetime', 864000);
at the very top of your bootstrap file.
Make sure session.auto_start is off in php.ini
