Getting a list of Client variables
To obtain a list of the custom client parameters associated with a particular client,
use the
<cfoutput>#GetClientVariablesList()#</cfoutput>
The
of the Client variables for the current application. The standard system-provided
Client variables (CFID, CFToken, URLToken, HitCount, TimeCreated, and LastVisit)
are not returned in the list.
Deleting Client variables
Unlike normal variables, Client variables and their values are not stored in volatile
memory and persist over time. To delete a Client variable, use the
DeleteClientVariable
<cfset IsDeleteSuccessful=DeleteClientVariable("MyClientVariable")>
The
specified by
CFML Reference.
Also, using the Client Variables page of the ColdFusion Administrator Server tab, you
can edit the Client variable storage to remove Client variables stored in either the
Registry or a database after a set number of days. (The default value is 90 days when
Client variables are stored in the registry, 10 days when stored in a data source.)
For more information about setting timeout values, see Advanced ColdFusion
Administration.
Note
You cannot delete the system-provided Client variables (CFID, CFToken, URLToken,
HitCount, TimeCreated, and LastVisit).
Using Client variables with cflocation
If you use the
Client.URLToken is automatically appended to the URL. You can suppress this
behavior by adding the attribute
Client variable caching
All Client variable reads and writes are cached to help decrease the overhead of client
state management operations. For information on variables and server clustering,
see Advanced ColdFusion Administration.
