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 should be defined through this administration page and default values set, however there are other mechanisms that can be used:

• 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 express (session.var.set).
• Imported at runtime dynamically, for example by pulling in additional user attributes from LDAP and assigning them to session variables.
