Expired Link Blocker
This plugin allows setting an expiration date for unique links or passwords in forms and surveys that were distributed via E-mail or Restricted by Unique Codes methods. After the unique links or passwords expire, respondents can either be redirected to a certain website or see an info message.
To apply this plugin, specify the following parameters:
*Days to Live - Specify the number of days the unique links and passwords should be active.
Redirect URL - Indicate the URL to which respondents will be redirected after the link or password expires.
Info Message - Indicate the message that respondents will see after the link or password expires.
You have to specify either Redirect URL or Info Message parameter; only one of these fields is mandatory. If you specify both parameters, a respondent will see the Info message when the unique link or password expires.
