52 Chapter 2: ColdFusion Tags
Usage
This tag is typically used in the Application.cfm file, to set defaults for a ColdFusion application.
This tag enables application variables, unless they are disabled in the ColdFusion Administrator.
The Administrator setting also overrides the
sessionManagement attribute. For more
information, see Configuring and Administering ColdFusion MX.
Server, application, and session variables
When you display, set, or update variables in the server, application, and session scopes, use the
cflock tag with the scope attribute set to the following value:
• For server variables, specify "server"
• For application variables, specify "application"
• For session variables, specify "session"
For information about locking scopes, see
cflock on page 221.
If ColdFusion is running on a cluster, you must specify
clientStorage = "cookie" or a data
source name; you cannot specify "registry".
clientStorage Optional registry How client variables are stored:
• datasource_name: in ODBC or native data
source. You must create storage repository
in the Administrator.
• registry: in the system registry.
• cookie: on client computer in a cookie.
Scalable. If client disables cookies in the
browser, client variables do not work.
setClientCookies Optional Yes • Yes: enables client cookies
• No: ColdFusion does not automatically send
CFID and CFTOKEN cookies to client
browser; you must manually code CFID and
CFTOKEN on the URL for every page that
uses Session or Client variables.
