<@PURGE [NAME=name] [SCOPE=scope]>
Used to remove a variable from a scope, or to remove all variables from a scope.
Note:
Purging variables in the cookie scope does not cause the
Web browser to forget a cookie. If you want to make a Web browser
forget a cookie, you must set the expiry time to immediate, for
example, "in -1 days" in the Properties dialog box for a cookie
variable when assigning values to variables with an Assign
action.
This meta tag cannot purge variables of system scope.
The following examples demonstrate how to remove a variable from a given scope:
<@PURGE NAME="foo" SCOPE="user">
