Something simple!? Sessions - admin.localhost to main.localhost

[Dave Mateer]

Hi

Why does the following code allow me to keep the same session when in
the same sub domain (ie admin.localhost ), yet not when I goto another
related domain eg main.localhost?

I would like to have the same session on the related domain. I bet
the solution is really simple <grin>!...

Kind Regards

Dave.

Using IE6. Win NT, Apache 1.3.27, PHP 4.3.2.

php.ini file - shown at end of message (apologies for length).. is
actually a copy of a PHP4.3.0 ini file (problem here?)

hosts file in windows:

127.0.0.1 localhost
127.0.0.1 admin.localhost
127.0.0.1 main.localhost

httpd.conf

setup for VirtualHosts
eg
ServerName admin.localhost .com


// session_test.ph p -- located in admin.localhost
<?
session_start() ;
echo "id is " . session_id();
?>
a href="http://admin.localhost/session_test1.p hp" next

a href="http://main.localhost/session_test2.p hp" next

// session_test1.p hp -- located in admin.localhost
<?
session_start() ;
echo "id is " . session_id();
?>

// session_test2.p hp -- located in main.localhost
<?
session_start() ;
echo "id is " . session_id();
?>


php.ini relevant code:

session.save_ha ndler = files
session.save_pa th = \temp
session.use_coo kies = 1
session.name = PHPSESSID
session.auto_st art = 0
session.cookie_ lifetime = 0
session.cookie_ path = /
session.cookie_ domain =
session.seriali ze_handler = php
session.gc_prob ability = 1
session.gc_divi dend = 100
session.gc_maxl ifetime = 1440
session.bug_com pat_42 = 0
session.bug_com pat_warn = 0
session.referer _check =
session.entropy _length = 0
session.entropy _file =
session.cache_e xpire = 180
session.use_tra ns_sid = 0

Dave,

From php.net, the section on session functions, and the function
"session_set_co okie_params", it was posted by a person who just doesn't
want to receive junk mail (it was not me). Basically you have to tell
the browser that the domain is domain.com, not sub.domain.com. It's
more of a client issue than a server issue.

ok. hope this works. first time posting

heres a quick little snippet I came up with to pass sessions between
lots of sub domains or c names. it also contains an array walker for
reading and outputting the contents of the current array(in this case i
use it for http_session_va rs)

ex:

https://www.fluidideas.com

chat.fluidideas .com
mypage.fluidide as.com

https://www.mypage.fluidideas.com

these will all have access to the session.

!!!BEGIN CUT!!!

session_set_coo kie_params ( time()+9999999 , "" , ".fluidideas.co m" );

if ( $HTTP_COOKIE_VA RS[session_id_set] )
{ session_id( $HTTP_COOKIE_VA RS[session_id_set] ); }
session_start ();
Function session_walker( $Array)
{
If ( !Is_Array($Arra y) ) Return $Array;
Reset($Array);
While( List( $Key, $Value ) = Each( $Array ) )
{
If ( Is_Array( $Array[ $Key ] ) )
{
$Array[ $Key ] = session_walker( $Array[ $Key ] );
}
Else
{
echo "key -> " . $Key . "
\n";
echo "value -> " . $Value . "
\n";
}
}
Return $Array;
}

!!!END CUT FOR SESSION INCLUDE!!!
!!!BEGIN CUT!!!

$user_session_i d = session_id();
setcookie("sess ion_id_set","$u ser_session_id" ,time()+9999999 ,"",
".fluidideas.co m", "");

session_registe r("user");
session_registe r("password") ;
session_registe r("email");

!!!END CUT FOR LOGIN!!!

now this example will allow the session to carry the data from sub
domain to sub domain and it only has one flaw that i've noticed. NS 4.7
is the only browser I've seen this in (also use mozilla .8 and IE5.5)
but if the domain doesnt contain a c name the sessions wont pass.

ex: fluidideas.com not www.fluidideas.com

If someone can come up with a fix to this please email me. Thanks
