Allows the setup of a dedicated session cache distinct from the normal XF cache

Defines a "sessionCache" section in addition to of a "cache" section. Takes all the same options, except $config['cache']['sessions']

Note;

• if no 'sessionCache' section is defined or it is disabled, falls back on existing cache/mysql storage
• Xenforo Session handling does not interact with php sessions
• Does not affect installer session or admin sessions

Migration

A migration script is provided which knows how to copy MySQL or Redis Cache sessions to the new Session Cach Configuration.

Copying (from) memcache sessions is not supported.

For copying Redis/MySQL sessions to a separate cache: copy_sessions_to_cache.php

1. Copy copy_sessions_to_cache.php to somewhere on the webserver.
2. Edit the line:
   
   Code:

   $dir = __DIR__ . '/html';

   To point to the webroot.
3. Install add-on, configure sessionCache but disable.
4. Run migration script.
5. Configure sessionCache to be enabled.
6. Note; some sessions will be lost, but not a large number.
