Memcache session sharing under the same primary domain

This configuration is suitable for session sharing with multiple servers with the same primary domain name .

For example: www.lee.com, bbs.lee.com (multiple subdomains).

Configure session Save in Memcache:

Ini_set ("Session.save_handler", "memcache");

Ini_set ("Session.save_path", "tcp://127.0.0.1:11211");

* * Multiple Memcache servers are separated by commas:

**ini_set ("Session.save_path", "tcp://127.0.0.1:11211,tcp://127.0.0.1:11211");

Ini_set ("Session.cookie_domain", ". lee.com"); //Specify the domain name that the cookie is saved in, the same domain name is consistent with the session_id saved under the browser.

If the Memcache client is an libmemcached-based memcached extension, it is configured as:

Ini_set ("Session.save_handler", "memcached");

Ini_set ("Session.save_path", "127.0.0.1:11211");

Ini_set ("Session.cookie_domain", ". lee.com");

Principle: The sessions under different servers are stored in memcache and have the same session_id.

Note:

* * Local virtual machine test:

Need to configure 192.168.1.20 www.lee.com bbs.lee.com

* * The subdomain cannot be accessed until bbs.lee.com is specified.
