Choosing a client variable storage method
Once you have enabled client state management, you then have to determine where
you want to store client variables. The system-wide default is for client variables to be
stored in the system registry. But your site administrator can choose to store them
instead in a SQL database or in cookies.
There are two steps to change client variable storage: first, setting a client variable
storage option in the Variables page of the ColdFusion Administrator, and then, noting
the client variable storage location in the CFAPPLICATION tag. See Administering
ColdFusion Server for information on using the ColdFusion Administrator.
You use the CLIENTSTORAGE attribute in the CFAPPLICATION tag to specify where
you want to store client variables, providing one of three values:
Registry
The name of a configured client store
Cookie
If no ClientStorage setting is specified, the default location, as noted in the ColdFusion
Administrator Variables page, is used.
The following example shows how you enable client state management using a sample
database called mydatasource.
To note the client variable storage method:
1.
Open the file
follows:

the values set in other storage options are unavailable.
