I have read that before. But what I need
is an example-syntax of “variableTimeoutTrigger”
explaining how to specify the “HTTP URL” in it. Can someone do
that?
Thanks.

Not sure, that you have read this in the online manual:
variableTimeoutTrigger
User, application, domain, and custom scopes
Just before a user's, application's, domain's or a custom scope's variables
expire, the HTTP URL specified in that scope's variableTimeoutTrigger is
activated. (The time
after which variables expire is set in the configuration variable
variableTimeout.)
This URL could be used to execute an
application file that clears the database of temporary user session data,
purges the user name from a list of logged-in chat users, or many other
possibilities.
There is no default timeout trigger. To have a trigger execute upon the expiry
of each user's variables, you would assign the desired value to
variableTimeoutTrigger (in user scope) at some point during each user's
session. To set a trigger for a particular domain, you would assign to
variableTimeoutTrigger in domain scope in an application file being accessed
from that domain. To set a trigger for a particular application, you would
assign to variableTimeoutTrigger in application scope in an application file
being accessed from that Tango application.
The URL in this configuration variable cannot contain meta tags because the
trigger mechanism does not evaluate meta tags. Nevertheless, you can include
user-, application-, or domain-specific information in the URL by including
meta tags in the assignment to variableTimeoutTrigger, which are evaluated at
the time of the assignment.
mailDefaultFrom
userAgent
variableTimeout
variableTimeout
User, application, domain, custom, and system scopes
The system scope version of this configuration variable determines the default
period, in minutes, after which domain and user variables expire. For user
variables, the expiry timer is reset to zero each time the user accesses
Witango Server. For application variables, the expiry timer is reset each time
the Witango application is accessed. For domain variables, the expiry timer is
reset each time a user from the domain accesses Witango Server. For custom
variables, the expiry timer is reset each time a variable in the custom scope
is accessed.
Setting variableTimeout to zero indicates that variables never expire. In
general, this value is appropriate for the domain scope only.
To change the expiry timeout period for domain variables only, assign the
desired value to variableTimeout in domain scope. For example, to specify that
"domain" scope variables never expire, make the following assignment:
<@ASSIGN NAME=variableTimeout SCOPE=domain VALUE=0>
Setting this variable with user scope sets the expiry timeout for the current
user, overriding the value in the system scope. For example, to specify that a
"User" scope variables expire in 15 Minutes, make the following
assignment:
<@ASSIGN NAME=variableTimeout SCOPE=User VALUE=15>
Setting this variable with application scope sets the expiry timeout for
Witango application, overriding the value in the system scope.
Hope this have answer your question
