Specifies the time interval at which to renew crawl authentication cookies.
Can be set in: collection.cfg
This optional parameter specifies the time interval at which to renew authentication cookies in a web crawl, in seconds.

Note:: You should only use this parameter if using pre-crawl authentication.
