how to share a session with other websites(subdomains) ?

[coolatt]

hi all,

I want to use session for storing username & password.
I will have a main page mainpage.mydoma in.com which will save username+passwo rd in a session on the server.

Now when i access email.mydomain. com i want it to retrieve the username+passwo rd from the session previously created by mainpage.mydoma in.com.

The web applications are hosted on the same machine using apache virtual hosts.
Someone plz advise...

thanks

If you want to be able to pass session data between subdomains you need to add/modify the following to the php.ini file.

session.cookie_ domain = .mydomain.com

If you are unable to modify the the php.ini file you can add the following before the session.start() function on any page which creates the session cookie.

ini_set("sessio n.cookie_domain ", ".mydomain.com" );

thanks for replying.

but how do i make email.mydomain. com access the data stored in the session created by mainpage.mydoma in.com ?

I want the mainpage domain to store username+passwo rd.
in session_test.ph p i put:

<?php
session_start();
$_SESSION['userName'] ="MyUserName";
$_SESSION['password'] ="MyPassword";

print "Session Test";

?>

then in session_show.ph p i put :

<?php
session_start();
if(isset($_SESSION['userName']))
{
  print "Session id: ".session_id()."<br>";
  print "Your session username: ".$_SESSION['userName']. "<br>";
  print "Your session password: ".$_SESSION['password']."<br>";
}
else
{
  print "Session does not exist";
}
?>

when i run the above test i get the session id.

just do one of the step which i have mentioned above

after that you can use it as it is,
i mean set $_SESSION['foo'] = "bar"; in one domain
and you can get it from the other domain
by $_SESSION['foo']

no other modifications are required

both email.mydomain. com & mainpage.mydoma in.com are already using sessions.

I tried to put the following code in email.mydomain. com but it didnt print theh username & password:

if(isset($_SESSION['userName']))
{
  print "Session id: ".session_id()."<br>";
  print "Your session username: ".$_SESSION['userName']. "<br>";
  print "Your session password: ".$_SESSION['password']."<br>";
}

else
{
  print "I cannot retrive data from another domain's session";
}

Is it because email.mydomain. com is already using session ??

which method you used ?

editing the php.ini or setting it on the php code?

editing the php.ini

then the session should be shared on the sub domains also. but remember to restart apache after changing the php.ini

yes i had restarted apache. any other steps i have to follow to make it work ?
plz advise on this.

[coolatt]

it does not work when both domains implement their own session management :-(
