I hadn't thought of that. However, we audit all user logins and logouts, as
well as all page requests. If the browser was pre-fetching the logout page,
we'd have 'user logout' entries in our logs, but the only notices we have
are for users logging in. If users were being logged out because of
pre-fetching, I'd expect to see each login entry have a corresponding logout
entry.


Is the potential for cached pages to be returned for a user NOT logged in?


Any pages which a user has viewed whilst logged in shouldn't be cached,
assuming the browser is respecting the headers. They are all sent with:

Cache-Control: no-store, no-cache, must-revalidate, post-check=0,
pre-check=0


How is your code determining if they need to be redirected back to the
login page?


The test is whether two $_SESSION elements are set and match ones in the 
database, plus whether the last page view by the user (stored in the 
database, updated on each request) was less than one hour ago.



What changes that information?


A page load changed the 'last page view time'. Nothing changes the other 
session data, except an explicit logout (which sets $_SESSION = array() 
and calls session_destroy).



Can you monitor it externally?


I'm not sure what you mean by 'externally'. Most of the site requires a 
login, so it's not possible for a third-party to monitor it if that's 
what you mean.

The only place session_destroy is called is in the logout function,

Session A is killed, your last login is always the current one.


Do you allow multiple, simultaneous logins per account?


No, but then each user is accessing their account from a single machine 
and browser anyway (i.e. they don't switch from desktop to laptop and 
then back again), so we don't even have people trying to have 
simultaneous logins.

How do you handle multiple logins?

If I login using my laptop and get Session A for my account and then I
login using my desktop and get Session B for my account, does Session
A get killed?

Do you allow multiple, simultaneous logins per account?

You have set gc_maxlifetime to 3600 seconds. How much expire time have

Because, every 3600 seconds, session data stored is considered as
garbage and php clears them out itself.


Yes, I'm aware of that. However, users are being logged out after a few 
minutes, not one hour of inactivity (which is what I'd expect with 3600 
seconds).



If your expiration time is more than 3600 seconds, then this will not
work. You need to increase gc_maxlifetime.


If you mean the expiration time of the session cookie, it is set to 0, 
which means it shouldn't be deleted until the browser is closed (or the 
user logs out, at which point it is deleted immediately).

If your expiration time is more than 3600 seconds, then this will not

For the other case, I'm clueless.

According to the PHP manual:

"session.cache_expire specifies time-to-live for cached session pages in 
minutes, this has no effect for nocache limiter."


So the value of session.cache_expire should be ignored, as 
session.cache_limiter is set to nocache.

I prefer to set expire-time to zero. So, browser will never forget session id.
In other case, if security requires, i usually set it to 24 hours, to
avoid some mystic problems, in case of misconfigured servers and/or
clients TZ; they are rare.

Hi:

Forgot to mention, you could check into the privacy
vs. server settings by doing:

   session_start();
   echo session_id();

on both pages.  If they're different, then
this is the problem.

If that works, I'd suspect that $row_scripture['ScriptureText']

If it doesn't, I'd suspect a combination of very strict

Angus:

First, don't trust anything that comes from the client -- period.

Second, Ajax is just another way to send stuff to the server. When 
the data gets to the server then authenticate and set a session 
variable to indicate such. This is not rocket science, but if you 
don't do it right you'll leave a crater.

No, you're right and my url's are clean of SID's -- they always have been, that 
was the default.

The "problem" I was trying to figure out was how the use of SID's cause SE's to 
fail and how that works. I figured that once I understand how that worked, then 
I could keep from doing it. I just needed to "see for myself" what it was. You 
know, one of my "wonder why this works" studies.

While the problem wasn't present for me, which at the start of this I wasn't 
sure about, I did learn how it works and why SE's have problems with indexing 
url's that have "?" in them.

For those interested in this thread, this is what I believe is happening.

If you have a web page that uses SID's in it's url, then it appears to a SE as 
something like this (using one of my sites as an example):

http://ancientstones.com?PHPSESSID=1234

and not like:

http://ancientstones.com/

So the SE grabs the page with the SID. The next time it travels your site, it 
see's:

http://ancientstones.com?PHPSESSID=5678

and grabs that page. After a while, Google has numerous duplicate pages and has 
to pick one to be representative of your site and store all the others into 
it's supplemental index.

Now when Google determines PageRank for your site, it does so by calculating 
how many sites link to your site (simple version). If Google has picked:

http://ancientstones.com?PHPSESSID=5678

to be THE representative for your site, then you're sunk because no one uses a 
SID in their link to your site. Your site will always have a PR of 0 -- as it 
is with the referenced site. While the site ranks very high (currently #1) in a 
Google search for "Custom Tile Medallions", it has a PR of 0. I was trying to 
figure out what was happening and if there was something I was doing in using 
php caused the low PR. I found that PHP wasn't the problem -- and now I know 
that.

At least, that's the way I understand what's going on -- if I'm mistaken, 
please correct me.

use_trans_sid (I think) will append the sessionid to all pages, so instead of:

/page.php

it will become

/page.php?PHPSESSID=x

much the same as if you do:



Bots don't like that, so where possible turn use_trans_sid off (check manual 
about when/how you can do this).



Chris:

Thanks -- after your lead, I found that my site's session.use_trans_sid was 
turned off by default.

So, it wasn't the problem I thought it might have been.


So your page urls don't automatically append the session id to the end? 
I might have the wrong variable name so if you're still seeing them, I 
obviously have it wrong...

I used to use a database table which housed their information, and their
cookie housed their sessionID that the server assigned them when they
logged in.  Grabbing the sessionID only from the cookie (and their IP) I
was able to log most people in (even "dynamic" IPs don't change THAT
often).  For those whom were dealing with a changed IP, the system had
them verify just their password.  Wrong password dumped them back out
and asked for full login information.  no browser issues at the time.

i recently started using PHP's sessions.  i am finding that the sessions
seem to "expire" after 20 or 30 minutes -- or, at least the variables
which i set, within $_SESSION, are getting cleared after this relatively
short amount of time.

before calling session_start(), i do a few initializations:

ini_set('session.use_cookies', 1);
ini_set('session.use_trans_sid', 0);
ini_set('session.save_handler', 'files');
ini_set('session.serialize_handler', 'php');
ini_set('session.name', 'session-id');

i am not setting the 'session.cache_expire' INI variable, and even did a
check to make sure it was not being modified, and i found that it
contains the default value of 180 (minutes).

furthermore, the *cookie* is not expiring.  i've also checked
'session.cookie_lifetime', and it is 0 (zero, for "until browser is
closed").  i've also checked the browser's cookie list, and the cookie
is still around at the time that i lose my session variables.

does anyone have any ideas as to why i may be losing my session
variables so early?


Check session.gc_lifetime or similar. That is the garbage collection 
routine that goes through and deletes any session data files (in /tmp or 
wherever your setup puts them) that are older than that config setting 
value.

Yes it does. But it doesn't erase the session values (it seems that's
what you think is happening?).

I think what you need to do (I do this sometimes too) is start from
scratch and create a very basic test page that works as expected. Then
slowly add in the features you want. It'll give you a much greater
understanding of how things work and where you're going wrong. Sure it's
tedious but it'll help you in the long run.

Here is a good base to start with:

Sorry bout that little mistake. You right I mean to check to see if
$_SESSION['loggedin'] == "yes"; That doesn't make a difference as it 
turns out. The reason that I immediately change this is that I want the 
content of the page to change, and in order to do that I want to stop it 
from going into this code? Actually I am not going to do this, I will 
use another variable, but by setting $_SESSION['loggedin'] to 'no' it 
should not go into this test, but it somehow does? Is it to do with the 
link:

does this call the script again, just as an action="script.php" in a 
form would? Cheers for the help on this.

No session_start(); can go anywhere. It's just that it appears that your

not really, well you can but I can't think

you have to call it before you use the session
(i.e. data stored in it).
if so I imagine that this means a single script

it can. maybe if I rewrite you code a little
it will help you understand:

session_start(); // always start the session.
// you want something more secure as a login procedure!
if($_POST["username"]=="rory") {
// if user logs in as rory
// then mark the user as logged in

$_SESSION['loggedin'] = "yes";
}

Put session_start(); at the *very* beginning of your script. See if that
helps.

One reason is for security. You cannot ever rule out the possibility of 
a user injecting someone else's data into the session to get access to 
information that he should not have. Of course he can fake the userid 
too. That's why each time you retrieve the userid from the session  you 
should check if that id has been logged in. I do this (so do many 
others) by keeping two column table with session id and userid in it.

You should only save the userId in the session, everything else should 
be retrieved from your database using that id.


Now let's say user 1 logs in, his session is registered (with userid from 
database is 5 and first_name is XXX)
Then another user logs in, again his session is registered (with userid from 
database is 1 and first_name is YYY)

 

Are both user's in the same computer? then there may be a question about 
the old cookie being sent back to the server (if it's expiration time 
has not been exceeded). If the users are not using the same computer the 
chances are you have a bug in your code.

Now user 1 leaves the pages (closes the browser) and user 2 uploads a 
document (with my own script).

When the document is succesfully uploaded i display this:
 PHP Code
 echo ($_SESSION['first_name']).", the document has been succesfully 
added";
 echo ($_SESSION['userid']);


This results in the folowing output:
YYY, the document has been succesfully added
5
Meaning the $_SESSION['first_name'] is correct, but the $_SESSION['userid'] 
is the one of the user who logged out...

Now when using user_id in all places it seems to work correctly...
Is userid something that is defined by the server when making sessions?
 

no.
If not, i don't have any clue what is going wrong...
Can someone help me on this? So i know what is wrong?
 


Thx in advance

Re: [PHP] PHP Sessions Question

2004-07-08 Thread Tim Traver
It could be a case that your provider is load balancing across several 
machines. If they are, and they aren't storing the session data in a 
central location, then that might account for the issue.

That would explain the intermittent failure. The user might be making 
keepalive requests to the same box and being ok, and then get bounced once 
it hits a machine that doesn't have the session data...

You might ask them about it...

What kind of problems could be happening server-side that would result in

I have a PHP / MySQL application that's been running at a host provider for
almost a year now.  PHP sessions are used to track logged in users, For
example, $_SESSION["UserID"].  If the UserID isn't stored as a session
variable, the user must not be logged in, so prompt them with a login
screen.

Most recent updates were made last week and everything has been working fine
until this afternoon.  Session data is somehow being lost.  It seems random.
A person will be logged in and navigating through the site when they
suddenly get a login screen.  They'll log back in and continue navigating
for a little while when it will happen again - sometimes within seconds and
othertimes within minutes.  Sometimes it won't even happen for 30 minutes
and then it suddenly begins to occur again.

Thanks in advance for any ideas or recommendations that I can forward to my
hosting provider on how to fix the problem.

I think you need to restart PHP to pickup the new php.ini changes.

This still looks like PHP is not looking for the php.ini file where you
think it is.  I strongly suggest you follow the previous advice to work out
where PHP is actually expecting your php.ini to be, before you have a need
to change another initialization parameter.

As sending cookies is pretty much a generic procedure which is not platform 
dependent it would suggest that your WinXP box is broken (needless to say I'm 
assuming that you have already ensured that your browser is configured to 
accept cookies). Have you tried any other browsers/platforms?

The above snippet means it works on  his linux box which is why i suggested to see if

Re: [PHP] PHP Sessions - Cookies Not Saving

2004-03-04 Thread Paul Higgins
When I do:  print_r($_COOKIE); I get the following:
Array ( [PHPSESSID] => 11781ce29c68ca7ef563110f37e43f38 )
Does that mean its setting the Cookie?  I can't see the cookie on my 
computer.  I don't have cookies disabled because I'm getting cookies from 
other sites.  The privacy setting is set to Medium.

This is the case with IE.  If I'm in my CMS and ctrl-N to get a new
window, I can operate under both windows using the same session.  If I
open a new instance of IE and go to a page in the CMS beyond the login
screen, it boots me back to the login screen.

Perhaps I should have elaborated a bit more.

Browser instance A:
1. Request http://example.org/foo.php
2. PHP assigns PHPSESSID of 12345
3. Returned page has a link for http://example.org/bar.php?PHPSESSID=12345
4. Request http://example.org/bar.php?PHPSESSID=12345

Browser instance B:
1. Request http://example.org/foo.php
2. PHP assigns PHPSESSID of 67890
3. Returned page has a link for http://example.org/bar.php?PHPSESSID=67890
4. Request http://example.org/bar.php?PHPSESSID=67890

Because A4 and B4 are different requests, they get different responses. So, in
a way, the server is able to distinguish between the two instances, but only
because of that. If instance A sends the request in B4, it will get the same
response as instance B would have.

That wasn't a great explanation, but maybe it is at least better than my last
attempt.

This is very interesting. I might try to research this a bit more and see what
the motivation was for doing this. From a user perspective, it seems very
counterintuitive. Thanks for the info.

 It seems to me a better example of what he is saying would be:
http://example.org/foo.php?PHPSESSID=12345
vs.
http://example.org/foo.php?PHPSESSID=67890

But I was talking about cookies anyway.  Which is where different browsers
have different behaviors.  In IE, by default, it will not pass a cookie from
a new browser window.  In Mozilla, by default, a new window keeps all the
cookies currently set.  I've mostly used IE, so I've always thought that it
never passed cookies from a new browser window.  Apparently, it just depends
on which browser you're using and how it is setup.

What John is explaining here is that the URLs could be different if that is how
the session ID is propogated, thus making the requests different (they're for
different URLs). So, if you click a link from:

http://example.org/foo.php?PHPSESSID=12345

it could be for:

http://example.org/bar.php?PHPSESSID=12345

Hope that helps.

Another test:

I just downloaded and installed Mozilla (1.5).  I logged into my site,
opened another window, and was logged in there also.  I logged out of the
second window, hit a "Home" link on the first window, and got a login
screen.  This is new behavior for a browser for me, but now I understand how
it works.  Thanks for the discussion.

That has been my point all along.  Perhaps I misunderstood you:

"there is no way for a remote Web server to distinguish between two
instances of the
same browser running on the client machine."
vs.
"The problem is the php script doesn't know that the browser you
 opened (that give you back the login screen) is even related to the
 other browser window."

Aren't these almost exactly opposite statements?
Isn't the web server distinguishing between the two instances?   Using the
cookie?

This is entirely up to the client, deciding to send a cookie or not
when opening a new browser window.  You can even turn the behaviour,
you describe, off in IE.

The problem is the php script doesn't know that the browser you
opened (that give you back the login screen) is even related to the
other browser window.  All the php script knows is that you simply
don't have a cookie.

So you're saying if the session ID is passed in on the URL it will work.
But I'm using cookies.  The only thing that gets passed on the URL is a
pagename.  Perhaps there is something funky about my setup, but it has
always worked this way for me.

Hi Rob.  That seems perfectly logical.  I've written a Content
Management System which (when it's finished in a couple of months ;o)
run the website at the university where I work.

I can presently open an instance of the CMS in IE, login as admin, then
open a new window and request another instance of the CMS, and login as
a less-privelidged user.

I can then use these two separate instances and work as two individual
users in the CMS at the same time.

I open a web browser (IE) and login to my application.  I open another

If you are not relying on a cookie based session, then this will work. Each
login could be assigned a different session ID, so the requests for each
browser will be different because of the different session IDs.

I will test it, because it seems I don't understand this issue as much as I
could.  But I can already tell you results I see right now:

I open a web browser (IE) and login to my application.  I open another
window (IE) and goto the web application, and it asks me to login.  This is
all on the same computer.  (As I've explained all this before.)  Now,
perhaps I don't know what I'm talking about, and this is a different issue.
If so, I'm pretty sure you'll certainly try to set me straight.  If not,
then it certainly seems relevant to the discussion, and that my one client
(IE) is sending two different requests from two different windows on the
same computer.

So there is a way, and it's not true.

Test it yourself.  Login to a PHP app using a standard browser and session
cookies and see for yourself.  I understand the philosophy of the web server
only seeing what the client sends it, but it looks like my client (IE6,
right here) does send different requests per instance.  It's not just 'in
theory.'

It can, and it is.

The only way a Web server could distinguish between them is if the browsers
sent something unique per instance within the HTTP request. So, you could write
a browser that does this in theory, but that doesn't really do you much good
unless you can convince your users to use it.

It would be very unusual behavior, so I doubt anyone would want this.

That can't be true.  I don't claim to understand exactly how it works, but
here is what happens for me.  I have an application that I log into.  Once
I'm logged in, if I open the URL in another browser window, it just gives me
the login page.  My guess is that the first browser window is passing a
cookie identifying the session that the second one doesn't know about.  In
your case, when you're not using cookies, the session ID must be passed on
the URL.  I don't know much about using trans_sid, so i can't help you
further.

I'm not sure if this fits your definition of "new browser instance", but there
is no way for a remote Web server to distinguish between two instances of the

I can't remember where i saw it (i think it was on a mailing list), but
someone said it'll only check /sbin/sendmail, which seams to be the
case. sendmail.path is set to '/usr/sbin/sendmail' in php.ini, but that
doesn't has an effect.

well, either way it hasn't been compiled in so a recompile will be
needed. it's only a 10 minute job anyway.

During the ./configure part of the installation, PHP checks for

function mail() isn't complied in.

I just get 'call to undefined function mail()' in x/y.php on z.

Aside from this, PHP's running like a dream. I haven't had a single
problem (other than mail() not working, but I found that's because I use
/usr/sbin/sendmail, not /sbin/sendmail, so I'll just need to recompile).

Although it's running under httpd, surley the fact that PHP's not
writing to the files on the drive (only 'touch'ing them so to speak) is
more of a PHP problem than an Apache problem?

Re: [PHP] PHP & Sessions generates Segment Faults

2003-01-22 Thread Justin French
I can say with near certainty that there is a problem with the session
handler you've chosen, for you to be getting these segfaults.  As I pointed
out, and as you've stated, if the sessions work fine with the 'files'
handler type, then the issue must be with the alternate handler.

So, if you wrote it yourself, perhaps it's got a bug.
If it's a library script, perhaps it has a bug, or has a FAQ, or some
support.

There's also the option that there's a bug with PHP in this/these version(s)
which is causing the problems.

Is there a reason why you can't just use 'files'???

I was unable to get it to run, I've setup the most basic session handler i

which probably means the child handling my request segment faulted.

I've already tried several different DB libs and Session handler libs, I'm

One thing that really bugs me though, is that if I don't touch the

EVERYTHING works just great! This kinda makes me think all the DB libs I

however
register_argc_argv is OFF on the server with problems.

The server is a Sun Cobalt server running some form of Linux.

My local machine that I work on is WinXP Pro using PHP 4.3.0, on this

No no no... check the output of phpinfo(), or check your php.ini file to see
if the directive "register_globals" has a value of ON or OFF.

This is more than likely the problem I think.

Also check the same value on your local machine.

Re: [PHP] PHP Sessions

2003-01-21 Thread Tim Thorburn
Ok, here's the sample code I found in one of my PHP books - it doesn't work 
exactly like my original script for checking passwords, but it does a close 
enough job to let me know that the sessions aren't staying registered.

I could ask my host if anyone else has had problems, but that would mean 
being able to get them on the phone, find someone who speaks English, and 
then hope that person has any kind of experience with Linux/PHP - which I'm 
quickly finding does not exist.

As it is a shared hosting situation, and I have no shell access (through 
telnet or SSH), I cannot check the php.ini file to see.

authmain.php

session_start();

if ($userid && $password)
{
// if the user has just tried to log in

$db_conn = mysql_connect("localhost", "login", "passWord");
mysql_select_db("databaseName", $db_conn);
$query = "SELECT * FROM userlogin WHERE user='$userid' AND 
passwd=password('$password')";
$result = mysql_query($query, $db_conn);
if (mysql_num_rows($result) > 0)
{
// if they are in the database register the user id
$valid_user = $userid;
session_register("valid_user");
}
}
?>


Test Sessions





if (session_is_registered("valid_user"))
{
echo "You are logged in as: $valid_user Log out";
}
else
{
if (isset($userid))
{
// if they've tried and failed to log in
echo "Could not log you in";
}
else
{
// they have not tried to log in yet or have 
logged out
echo "You are not logged in.";
}

// provide form to log in
echo "";
echo "";
echo "Userid:";
echo "";
echo "Password:";
echo "";
echo "";
echo "";
echo "";
}
?>

Members section



members_only.php

global $userid;
session_start();

echo "Members only";

// check session variable

if (session_is_registered("valid_user"))
{
echo "You are logged in as $valid_user.";
echo "Members only content goes here";
}
else
{
echo "You are not logged in.";
echo "Only logged in members may see this page.";
}

echo "Back to main page";
?>

Does sessions work at all for the other people on your shared server? Ask 
your
host whether anybody else has complained.

> PHP 4.1.2 (doesn't work)
> '--enable-mm=shared'

Would this have anything to do with it? Apparently there could be problems
with storing sessions in mm:

  http://marc.theaimsgroup.com/?l=php-general&m=104311365417871&w=2

Check in php.ini whether sessions are file based or using mm.

Sorry I'm a bit late in on this thread but I know there is a problem with
sessions with 4.1.2 with IIS 5 over Win2K... is that your platform? I
encountered it a while back and there is a hack/workaround which I can dig
up if you need it...

Yes, I believe you're right -- but on Windows only.  Sessions in that specific version 
of PHP were accidentally read-only -- so you could appear to set values in the 
session, but they'd never show up in subsequent pages...!

Bug reports http://bugs.php.net/bug.php?id=16043, http://bugs.php.net/bug.php?id=16102 
and http://bugs.php.net/bug.php?id=16202 are relevant.

Wasn't it 4.1.2 that had broken sessions? I remember one version that
came out that was just broke and you had to do a bunch of workarounds to
get things to work normally. Was that it?

Are you using the $_SESSION array or relying on register_globals?

Yes, the examples from the manual do work on the server using PHP 4.2.2 - 
however they do not work on the server using PHP 4.1.2.

I've been using this same script for many sites with PHP versions 4.0.6 
thru 4.2.2 with no problems until now which leads me to believe that I must 
attempt to change a PHP setting through .htaccess since it is hosted on a

I've tried the example from the manual on several other sites - works

Again, does the simple example from the manual work? If it works we can
eliminate config settings and concentrate on your code.

RE: [PHP] PHP Sessions

Hi,

I'm using PHP 4.1.2 on the server with problems - it's hosted on a shared

Here are the settings attained from phpinfo(); for the server that does not

After the Configure Command of each is a list of settings that differ.

Much thanks for responding so quickly and at such a late hour!!

Does the simple example from the manual work? If not, what does the php.log 
say? If it does work then what does your code look like?

What is the config of the "server with an attitude"? phpinfo()? Did you check 
for any differences between that and the servers that do work?
