|Preserve session variable into an SQL database|
|Session variables are W_VAR (W_SSTRING, W_INT) defined with the option S. They are loaded/saved on a user per user basis. Users (session in fact) are identified by a cookie.|
|bool auth (WEBSESSION_SQL_INFO &info, const char *passwd)|
|void exec (WEBSESSION_SQL_INFO &info)|
Return true if the user has supplied the proper password. By default, password are not validated. The component is only used to preserve session variable in that case.
At this point, session variable are reloaded and will be saved when this functag ends
