Appboard/2.4/builder/system administration/session variables

The Session Variable administration page allows the definition and default configuration for session variables within the AppBoard system.

Typical uses for session variables:

• storing environmental information that is subject to change such as database hostnames, usernames, passwords.
• associating extra information for domains and users, which can then be used for a variety of purposes such as modifying queries etc... This may be helpful in multi-tenanted deployments.
• a central place to store simple key information used in multiple places

Session variables can be used anywhere SHIM expressions are permitted using session.var.get.

There are a number of ways to set session variables:

• Session Variables administration page to define and set defaults
• URL parameters to override session variables (only allowed if configured this way)
• Explicitly set through the use of a SHIM expression session.var.set.
• Imported at runtime dynamically, for example by pulling in additional user attributes from LDAP and assigning them to session variables.
