Hi there,

Could someone tell me how to pass a session cookie to different subdomains, without passing it in url.
Thanks in advance.

You can configure PHP to use a specific cookie domain/path. I'm pretty sure (not positive, so this will require you to test it yourself) that if you only specify a host and tld (e.g. '.wrox.com'), the cookie will be available for all sub-domains.

For more info, read through the following manual pages (and the informative external links in them):
  http://www.php.net/session
  http://www.php.net/setcookie

The configuration option in PHP.ini that you want to look for is "session.cookie_domain".


Take care,

Hi Nik,

I've already found the answer in php docs
http://www.php.net/manual/en/function.setcookie.php
will try it tonight.

Thanks for your help.

setcookie() is a function that allows you to set a cookie variable, but you have to be careful about messing up your original session variable. If PHP handles setting and retrieving your session ID in a cookie, you're probably best off configuring PHP to create a cookie that works across sub-domains.

If you have written your own session handling functions (and, in my opinion, it sounds like a good idea for your multi-domain site to do so, especially if each domain is on a different machine. If you're using the same database server to store all your session data, you can use a cookie to store the session ID for all sub-domains, and each server uses the same session handling functions and database server to access that user's session.

If I'm not making sense, let me know.


Take care,
