Establishes a time during which the user data associated with a particular session is managed in the server memory (and in the user's web session). As a result, the database is not accessed for this purpose.
&GAMRepository.UserSessionCacheTimeout = Number_Seconds
Where:
&GAMRepository
Is a variable based on the GAMRepository data type.
Number_Seconds
Number of seconds during which the user data associated with a particular session is managed in the server memory (and in the user's web session). As a result, the database is not accessed for this purpose.
To increase performance, the time specified in this property implies that during this period the GAM application does not need to query the database to check the user session.
Every time the application queries the database to get information on the user session, the time is reset. Therefore, while the User Session Cache Timeout does not expire, the user information is retrieved from the web session if possible. When the time expires, and the user session is needed, the information is retrieved from the database and the cache is reloaded.
The cache is reset when the user logs out and logs in again.
The information cached is that of the GAMSession external object; it belongs to a specific user and so it is stored in the web session.
Note: When using the GAM Backoffice, the UserSessionCacheTimeout property can be configured by selecting Repository > Configuration > General Security Policy. It is shown with the description "User Session Cache Timeout (seconds)".
To set this property in the GeneXus code (by using the GAM API), the syntax is as follows:
&Repository.UserSessionCacheTimeout = &UserSessionCacheTimeout
The GAMRepositoryConfiguration Web Panel object is an example of where this property is used.
