Client Variables 73
Note
If you use the registry to store client variables, ensure that enough memory is
allocated for it.
To enable client variable storage in the registry as the default:
1 In the Client Variables page, select Registry. Click Apply.
2 To display a page in which to enable the automatic deletion of variables that have
not been used for a specified number of days, click Registry. Click Submit
Changes.
To enable client variable storage in cookies as the default:
In the Client Variables page, select Cookie. Click Submit Changes.
To enable client variable storage in a data source as the default:
1 In the Client Variable page, select a data source in the drop-down list.
2 Click Add Client Variable Storage. The Add/Edit Client Store page for your data
source displays.
3 On the Add/Edit Client Store page, select options for the data source, as
described in the following table. If you do not want to make changes, return to
the Client Variables screen using one of the arrows on the page.

Option Description
Purge data for
clients that
remain
unvisited for
[n] days Enable this option to periodically purge client data that has not
been accessed in a specified number of days, and enter a
number.
Disable global
client variable
updates Enable this option to prevent ColdFusion Server from updating
client variables for every page request. When updates are
disabled, ColdFusion Server only updates global client variables
when they are created and when they are changed. Disabling
updates helps improve the performance of application pages.
Create Client
database
tables Enable this option only when you configure a data source for
client variable storage the first time. ColdFusion Server creates
the tables necessary for client variables. If the data source has
already been configured, disable this option. Otherwise,
ColdFusion Server generates an SQL error because it tries to
create tables that already exist.
