This optional parameter specifies the time interval at which to renew authentication cookies in a web crawl, in seconds. For example, a value of 1800 would mean the webcrawler would renew the cookies every 30 minutes. This would normally be done by using the pre-crawl form interaction, using configuration defined in crawler.form_interaction.pre_crawl.[groupId].url to generate the cookies.

You should only use this parameter if using pre-crawl form interaction (as configured by crawler.form_interaction.pre_crawl.[groupId].url).

Setting the key

Set this configuration key in the search package or data source configuration.

Use the configuration key editor to add or edit the crawler.monitor_authentication_cookie_renewal_interval key, and set the value. This can be set to any valid Integer value.
