Hi thanks for the links it appears that its all in order also I'm not losing
SESSIONS on the redirect but somewhere else.
I have checked the garbage collection, disk space and other settings in the
PHP.ini file. ALL FINE.
So now I am really stuck and confused as to what could sometimes cause the
loss of these variables and other times it just works fine.
Is there possibly a way that I can call some function that will ensure that
the sessions are saved (I checked the manual - nothing much).
Any other ideas? Anything that you think might be causing issues?
Thanks
Angelo
Hi all,
I have solved the issue of lost session variables.
It appeared to be losing the SESSION variables when going from a POST from
HTTP to HTTPS, however it didn't always happen, so the logging allowed me to
narrow down where the losing was occurring.
The solution.
In my form that I post from the HTTP site, I put a hidden variable in there
and with the session variable.
In HTTPS it sometimes doesn't carry over the hidden variable therefore we
need to start the session with the old SESSION ID from the HTTP site.
So what I did was the following on the https site:
if (isset($_POST['sessionID']))
{
//http://stackoverflow.com/questions/441496/session-lost-when-switching-from
-http-to-https-in-php
// Retrieve the session ID as passed via the GET method.
$currentSessionID = $_POST['sessionID'];
//echo $currentSessionID;
// Set a cookie for the session ID.
$sessionid2 = session_id($currentSessionID);
}
Therefore setting the session ID with the session_id() function. This must
go before the session_start() function!!! Very NB!.
Hope this helps anyone who has a similar problem.
Regards
Angelo

RE: [PHP] SESSIONS lost sometimes
Since we are on the subject: I have the following similar problem: When testing page on internet explorer, I find that one tab's variables can affect another tab's variables. Thus when having the same web-site open and using SESSION variables but for different users, Internet explorer can become disorientated. This also sometimes happen when I have two separate browsing windows open with Internet Explorer for the same site. I have yet to determine if this is an internet explorer, or PHP or combination of the two that is causing this condition. To my understanding _SESSION variables should be maintained per session, tab or window. If this has been addressed already, my apologies, but thought it worthwhile to mention.

RE: [PHP] SESSIONS lost sometimes
It's not an issue, it's a feature. Thanks Arno...but it is a pain also. If I work with user A in Tab1 (window1), I want to work with user B separately in Tab2. When user in Tab2 logs off, I still want user A to work, and not suddenly have to re-login. Same with bank. If I work with my company account, then my personal account must not become an issue because I am on the same machine and site. I have no issue with using FF and IE to do testing as that takes care of browser compatibility testing at the same time :-), but I think when you start a new session with new values, it should be kept under that window/tab alone. Cookies can take care of more details, but my opinion is data should never be affected across windows/tabs unless the same user is logged in on botheven then I would expect PHP to keep data per session. Maybe it goes beyond being an IE or FF issue..the questiojn is...will PHP allow variables from session A become corrupted when session B is in progress when they should actually be handled seperately? In the end I think it is something I do wrong in PHP with the SESSION variables and how I clear themif so...I don't think PHP should allow clearing SESSION variables from other sessions. -Original Message- From: Arno Kuhl [mailto:ak...@telkomsa.net] Sent: 20 August 2009 10:03 AM To: 'Leon du Plessis'; php-general@lists.php.net Subject: RE: [PHP] SESSIONS lost sometimes -Original Message- From: Leon du Plessis [mailto:l...@dsgnit.com] Sent: 20 August 2009 09:44 AM To: php-general@lists.php.net Subject: RE: [PHP] SESSIONS lost sometimes Since we are on the subject: I have the following similar problem: When testing page on internet explorer, I find that one tab's variables can affect another tab's variables.

But in this case the Tab being opened is used with the same authentication details either via POST, GET or Cookie variables. The problem comes in when a totally different set of login credentials are being used (for the same tab/window).

RE: [PHP] SESSIONS lost sometimes
Hi, Just a re-iteration on the problem: Browser 1 has user A details Browser 2 has user B details User B logs off, then user A is suddenly in logged of status also. The method used to destroy the session is: // Unset all of the session variables. $_SESSION = array(); // Finally, destroy the session. session_destroy(); Problem. User's A session is also destroyed. The concern is, that this should not be the case. User A must happily continue to work. So, should PHP destroy the whole browser's session id's variables? My answer is No. User A and user B should have different session ids, if not, then it is wrong. A new window should have PHP to spawn a new session id (that is, the request does not come from an existing page where an id has been created already. If the ids are different, then session_destroy should only clear variables for relevant session_id, ie only User B's details In this example. The problem then probably lies in the session_ids being either the same for the two different logins (although they are on different browser) or session_destroy clearing data across sessions. (I will test that later). It would then seem that session ids is setup per location/machine by MS Windows as per Peter's explanation. Setting up profiles is the the resolution as suggested. Otherwise, it would be nice if Windows/IE/FF/PHP could identify when a BRAND NEW page is being opened and then create a brand new session id for that window/tab. It is not a huge issue, I was just wondering if someone else had the same annoying condition. I am happy with the responses and the functionality somewhere on a wish-list. Now Back to Angelo's SESSION problem which sounded like it could be related. Greetings!

RE: [PHP] SESSIONS lost sometimes
Thanks Ashley, I just want to iterate again that when a new page is opened by another existing page in a new browser or Tab, the session_id is already created and therefore the current way browsers work is in no way compremised. The new browser/tab would receive the session id along with GET or POST variables. What I am suggesting/hoping is that when a new browser is opened or a new tab is opened via the application, the protocols would reckognize that this is the first time the page is served and is not being called from another page. That is, a new page is loaded by the user entering it, and NOT by clicking login or some other link from an existing page. Yes, I know..that creates other scenarios, so is happy to not meddle with the way browsers work. It is just a limitation I will live with and can get by with it.

Re: [PHP] SESSIONS lost sometimes
Leon, Sessions are used on a per-domain basis. So, no matter how many windows or tabs you have open for mydomain.com it will be the same session for all. Having a different session start up for each window or tab would be a major pain. If you needed to keep track of a user ID, for example, you wouldn't be able to. As already mentioned you can use different browsers. You can also set up sub-domains which would each have their own sessions. Take care, Floyd On Aug 20, 2009, at 4:26 AM, Leon du Plessis wrote: It's not an issue, it's a feature. Thanks Arno...but it is a pain also. If I work with user A in Tab1 (window1), I want to work with user B separately in Tab2. When user in Tab2 logs off, I still want user A to work, and not suddenly have to re-login. Same with bank. If I work with my company account, then my personal account must not become an issue because I am on the same machine and site. I have no issue with using FF and IE to do testing as that takes care of browser compatibility testing at the same time :-), but I think when you start a new session with new values, it should be kept under that window/tab alone. Cookies can take care of more details, but my opinion is data should never be affected across windows/tabs unless the same user is logged in on botheven then I would expect PHP to keep data per session. Maybe it goes beyond being an IE or FF issue..the questiojn is...will PHP allow variables from session A become corrupted when session B is in progress when they should actually be handled seperately? In the end I think it is something I do wrong in PHP with the SESSION variables and how I clear themif so...I don't think PHP should allow clearing SESSION variables from other sessions. -Original Message- From: Arno Kuhl [mailto:ak...@telkomsa.net] Sent: 20 August 2009 10:03 AM To: 'Leon du Plessis'; php-general@lists.php.net Subject: RE: [PHP] SESSIONS lost sometimes -Original Message- From: Leon du Plessis [mailto:l...@dsgnit.com] Sent: 20 August 2009 09:44 AM To: php-general@lists.php.net Subject: RE: [PHP] SESSIONS lost sometimes Since we are on the subject: I have the following similar problem: When testing page on internet explorer, I find that one tab's variables can affect another tab's variables.

If different browser windows/tabs on the same client-side computer didn't share session info then you'd get the effect of being able to log onto a site with one browser window, but find in a second browser window that you were not yet logged on. Experience will tell you that you're logged on in both browser windows (try it with your online bank). It's not an issue, it's a feature. If you want to be able to use different browser windows as though they were different users then use different browsers e.g. IE and FF on the same client-side computer will look like two separate end users to the server, and they don't share session info or cookies.

The new browser/tab would receive the session id along with GET or POST variables. What I am suggesting/hoping is that when a new browser is opened or a new tab is opened via the application, the protocols would reckognize that this is the first time the page is served and is not being called from another page.

Re: [PHP] SESSIONS lost sometimes
The original problem.. server is losing session variables. I dont think PHP is not good at unset() ing variables while the script is executing. general logger will be of use in this case (especially when cant reproduce the problem every time). PEAR, Zend, FirePHP, files... any thing will do... try to log every thing related to sessions at the start of the page... session_id, $_SESSION super global, _SERVER['PHP_SELF'] do the same thing after the script exists... i had a similar problem earlier... a page in my app used to change $_SESSION['id']. It took me ages to find out the source... even grep was of no use... at last i was able to isolate the page that was causing this, with the help of logging. Of course, the main problem was that my production server has register_globals on, while my development server has them off. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It makes it a little easier for people to exploit holes in weaker PHP scripts.

Re: [PHP] SESSIONS lost sometimes
We have a server with a site that does some XML calls. After lots of testing I have found that the server is losing session variables. [8] Also the site goes from HTTP to HTTPS at some point but this isn't the issue as it loses the sessions as soon as they are set sometimes. Therefore I would like to know what I could check. I have read in other Can you clarify what you mean by losing sessions? Have you taken a network trace to see whether the client is consistently sending the session ID with every request? When the problem happens, is $_SESSION completely empty or is it only missing some variables? Does it seem to happen on any page, or only certain ones?
