192d36c5 | 13 | * BAO object for civicrm_cache table. |
14 | * | |
15 | * This is a database cache and is persisted across sessions. Typically we use | |
6a488035 TO |
16 | * this to store meta data (like profile fields, custom fields etc). |
17 | * | |
18 | * The group_name column is used for grouping together all cache elements that logically belong to the same set. | |
19 | * Thus all session cache entries are grouped under 'CiviCRM Session'. This allows us to delete all entries of | |
20 | * a specific group if needed. | |
21 | * | |
22 | * The path column allows us to differentiate between items in that group. Thus for the session cache, the path is | |
23 | * the unique form name for each form (per user) | |
