Description
Names the application, enables Client and Session scope variables,
and sets the client variable store to the myCompany data source.
Ensures that debugging output is not displayed, if the ColdFusion
Administrator enables it.
Specifies custom error handlers for request and validation errors
encountered in the application. Specifies the mailing address for use in
the request error handler.
Sets the Application scope variables, if they are not already set. For a
detailed description of the technique used to set the Application
scope variables, see
Sets the Session scope
of pages touched in this session. If the variable does not exist, creates
it; otherwise, increments it.
Sets two Variables scope variables that are used throughout the
application. Creates the current_page variable dynamically; its value
varies from request to request.
Includes a library of user-defined functions that are used in most pages
in the application.
